在三角形的辐射贴片和接地面之间加载一段微带线，在２．４５ＧＨｚ引入一个具有全向辐射特性的新模式，加上三角形贴片本身在５．８ＧＨｚ具有的定向辐射特性，组成了一个双频段双模式可穿戴天线。
天线的仿真结果表明，在低频处实现全向辐射特性，阻抗带宽为１．６％（２．４５～２．４９ＧＨｚ），可用于体表通信模式；在高频处具有定向辐射特性，阻抗带宽为４．３％（５．６７～５．９２ＧＨｚ），可用于体外通信模式。

The construction and materials of the antenna constrain its near-field region to occupy a very small volume so that materials near theantenna cause negligible de-tuning effects. Therefore the antenna maintains its pattern and efficiency in the presence of dielectric loading. As a dielectric-loaded antenna the MWSL1252 has a stablefiltering effect; attenuating signals from common cellular and ISM frequency bands by as much as 30dB without external filtering.0849096180-96-90-84Elevation Gain (G θ) For Azimuth (φ)0264270276Azimuth Gain (G φ) for Elevation (θ)Rev.Date Description Approved Checked PreparedMARUWA Antenna ProductsDocument №MEPS-12520042150101MWSL12520103 Feb. 15Issue of the first edition K.Inagaki F.Frimpong O.Leisten A second mode of installation is one in which the MWSL1252 isembedded into the housing with features surrounding theantenna causing a moderate degree of down-tuning. Though it iselectrically isolated from the device ground plane, through theaction of an integrated balun, the MWSL1252 antenna can beexpected to increase efficiency by up to 100% when integratedinto a ground plane due to constructive near-field signalreflections. This product is generally used in a class of smallportable devices that have slim styling so that there is no spacefor a ground-plane that is laterally disposed with respect to theantenna-axis. It is therefore specified as embedded into aground-plane that is co-planar with the antenna axis.The MWSL1252 is designed for applications with embedding configurations that tune theantenna from the free-space resonant frequency of 1593.5MHz to the GPS L1 frequency of1575.42MHz. Such configurations include the co-planar ground-plane as shown above with10mm offset between the circuit-board copper-ground plane and the side of the antennatogether with further de-tuning caused by the plastic housing of the product.For applications with more tight embedding MARUWA offers the MWSL1251 part which is tuned to a free-space frequency of 1603.5MHz.The MARUWA MWSL1252 antenna is designed for two modes ofinstallation.The first (and preferred) configuration is as a stand-aloneextenally mounted antenna (outside of the housing) with the black-capradome fitted (MARUWA part number: METC120X0158140101). Theantenna can be incorporated into a stand-alone package with a co-axialconnector output as might be configured in a screw-on packageformat. In such a configuration the MWSL1252 part may be embeddedwithin a plastic over-moulding. Alternatively the antenna can beconnected to an internal circuit board using the connection pads butwith the product housing closing into the groove of the black capradome. As an another alternative the customer may choose to designa radome of a different style. Such a design must be implemented witha suitable low-loss material which has the same dielectric loadingeffect as the MARUWA METC120X0158141010 black cap/radome.Typical Impedance Response Typical Return Loss Response Filtering Response Rev.Date Description Approved Checked PreparedMARUWA Antenna ProductsDocument №MEPS-12520042150101MWSL1252O.Leisten Cellular 900GPS L1Cellular 18003G Rx ISM 2.4190021102170-29-32-30-40-38-46-40-3K.Inagaki F.Frimpong 0103 Feb. 2015Issue of the first edition Frequency (MHz)S 21 (dB)24002480860970157517001800-26-36A set of match loci for a typical MWSL1252antenna is shown as plotted on a Smith chartwhich is normalised to 50 . The dielectric-loaded structure of the antenna causes thematch characteristic not to change significantlywhen is close proximity to the human body. Forexample the |S 11| response is remarkablyunchanged as a human hand is brought as closeas 5mm from the antenna.This MARUWA dielectric-loaded antenna technology delivers a major advantage with regard toimmunity to de-tuning when brought into close proximity to human tissues and other "in-use"causes of dielectric loading. The MWSL1252 antenna retains efficiency and polarisation near the human body. Conventional antennas may lose 5-10dB of gain or efficiency in similarcircumstances of use.The frequency stability of the MWSL1252antenna is further illustrated in the graph ofreturn-loss magnitude (in dB)for fourdifferent levels of dielectric loading (mmoffset from a phantom hand). Once again itdemonstrates that minimal detuning occursuntil the antenna is within 10 mm of thephantom hand.Page 6/6Embedding Information Pad Layout and designation Pad Number Function 1Ground 2Signal 3GroundDimensionsmm ± 0.1A3.2B1.45C1.7D0.5E1.5F3.5G 3.5Ordering Guide for the MWSL1252 AntennaMaruwa PartDescription MOQ Pack Size MWSL1252 with PBC-feed connection.MWSL1252SMWSL1252 with sleeve (for embedded use).Please note that when MWSL1252S or MWSL1252R parts are ordered the sleeve/radome parts shall be delivered in separate packaging and will not be fitted to the MWSL1252 product.

NANO mXTEND TM: MINIATURE AND HIGH EFFICIENCY BLUETOOTH/WI-FI ANTENNAUSER MANUALNANO mXTEND TM (NN02-101)NANO mXTEND TMMINIATURE AND HIGH-EFFICIENCY BLUETOOTH/WI-FIANTENNANN02-101NANO mXTEND TM | Bluetooth & Wi-Fi Operating range: 2400 – 10600 MHzBest for: 2400 – 2500 MHzDimensions : 3.0 mm x 2.0 mm x 0.8 mmWhat is the NANO mXTEND TM?The NANO mXTEND TM is the smallest Virtual Antenna® chip to date. Featuring a size of only 3 mm x 2 mm x 0.8 mm, this off-the-shelf chip antenna has been designed to fit almost every IoT device from entry-level to high-end products. The NANO mXTEND TM is enabled by Virtual Antenna® technology, thus featuring the unique properties of this class of products: easy to use; versatile, and broadly tunable. The NANO mXTEND TM is available for Bluetooth, Wi-Fi, Wi-SUN, and any wireless connectivity protocol operating in the 2.4 - 2.5 GHz band. Due to Ignion’s proprietary Virtual Antenna® technology, this chip antenna is non-resonant and therefore broadly tunable, enabling additional frequency bands to be supported by the same antenna part and released in the future.As with every other Virtual Antenna® chip, the NANO mXTEND TM is available through Ignion’s Antenna Intelligence Cloud tool, enabling predictable design and performance throughout the entire product development cycle. Moreover, the NANO mXTEND TM is built on a glass epoxy substrate, making its manufacturing broadly available and therefore resilient against shortage.Material: The NANO mXTEND TM antenna booster is built on a glass epoxy substrate.What is the NANO mXTEND TM used for?The NANO mXTEND TM is suitable for embedding an antenna into any wireless device requiring optimum performance in a small, cost-effective package for operating in the Bluetooth/Wi-Fi/Wi-SUN ISM 2.4 GHz frequency bands, including:▪Asset Trackers▪Smart Tags▪Earphones and Headsets ▪Wearables▪Logistic Trackers▪Health sensors ▪Animal Trackers▪Security Sensors▪Service Buttons▪Environmental Sensors ▪IoT Developer Kits▪Wireless Sniffing SensorsWhat differentiates the NANO mXTEND TM from other chip antennas?Like every other Virtual Antenna® product, the NANO mXTEND TM is frequency neutral, meaning that its frequency response is not determined by the antenna component but designed by the electronics engineer. Virtual Antenna® technology provides the broadest range of connectivity options with desired antenna performance in the smallest ever form factor. This unique technology enables the whole mXTEND TM range of components to become tiny, off-the-shelf, surface-mount (SMD) electronic chips while still providing connectivity with multiple frequency bands and meeting the requirements of most wireless devices’ architectures and form factors. Being non-resonant, the whole antenna performance can be customized through a shorter and easier design cycle by means of a matching circuit, while benefiting at the same time from a robust, reliable, and cost-effective manufacturing process because of the chip, SMD form factor. Also, the NANO mXTEND TM‘s architecture is not using ceramic materials to achieve miniaturization, which ensures a pervasive availability of raw materials thus making the supplychain resilient to shortage and price fluctuations.HOW TO EMBED A VIRTUAL ANTENNA®MECHANICAL SPECIFICATIONSASSEMBLY AND MANUFACTURINGPACKAGINGThe NANO mXTEND TM for Bluetooth/Wi-Fi 9 CORNER MOUNTING CONFIGURATION 9 MATCHING NETWORK 11 VSWR AND TOTAL EFFICIENCY 12 RADIATION PATTERNS, GAIN, AND EFFICIENCY 13 EDGE MOUNTING CONFIGURATION 14 MATCHING NETWORK 15 VSWR AND TOTAL EFFICIENCY 16 RADIATION PATTERNS, GAIN, AND EFFICIENCY 17 MECHANICAL SPECIFICATIONS 18 DIMENSIONS, TOLERANCES, AND RoHS 18 INK COLOR RANGE 18 RECOMMENDED FOOTPRINT FOR THE NN02-101 19 ASSEMBLY AND MANUFACTURING 21PACKAGING 23How to embed Virtual Antenna ®Design with Virtual Antenna ® in 1-2-3https://ignion.io/design-center/tutorials-webinars/STEP 2: Design your matching network1.

This section presents a suitable matching network for the corner mounting configuration (Figure 7). Please note that different form factors, RF ground planes, and nearby components may require a different matching network.If you need assistance to design your matching network beyond this application note, please contact *****************, or if you are designing a different device size or a different frequency band, we can assist you in less than 24 hours.

The antenna performance is always conditioned by its operating environment meaning that differences in the device, including differences in printed circuit board sizes, components near the antenna, displays, batteries, covers, connectors, etc. affect the antenna performance. Accordingly, placing pads compatible with 0402 and 0603 SMD components for a matching network as close as possible to the feeding point of the antenna element is highly recommendable. It is also recommendable to do this in the ground plane area, not in the clearance area. By tuning the matching network in your final design after your final surrounding components are in place (batteries, displays, covers, etc.) you will be able to optimize the antenna performance without changing the antenna part or the design.1 See terms and conditions for a free Antenna Intelligence Cloud service in 24h at:https://www.ignion.io/antenna-intelligence/VSWR (Voltage Standing Wave Ratio) and Total Efficiency versus Frequency (GHz).Figure 3 - VSWR and Total Efficiency for the 2.4 – 2.5 GHz frequency range as observed on the evaluation board EB_NN02-101_c_BT (Figure 1).2.4 – 2.5GHzNANO mXTEND™ ɳa 2400MHzɳa 2500MHz Min Max Av. ɳaOn the corner 54.9 57.1 54.9 63.2 60.1 Table 3 - Antenna efficiency comparison considering the evaluation board EB_NN02-101_c_BT (Figure 1).The NANO mXTEND TM operates at the required Bluetooth/Wi-Fi frequency spectrum with high-efficiency values.

智能天线使用手册
1、引言1.1、智能天线的基本功能〕智能天线定义N 列取向相同的天线按照一定方式排列和激励，利用波的干涉原理形成预定波束的阵列结构天线。
〕智能天线基本功能智能天线可以通过改变各天线阵列的激励，其中激励包含幅值和相位，利用波的干涉原理形成预定波束。
同时，TD-SCDMA智能天线接入到TD-SCDMA基站后，通过基站的实时自适应信号处理算法，能够自动地产生多个窄波束方向图，实现对移动用户的波束跟踪，并自动地抑制干扰方向的副瓣电平。
从而降低了系统的干扰，提高了系统容量，达到空分多址的目的。
1.2、智能天线与GSM天线的区别〕结构组成区别智能天线由两个或以上天线阵列组成，而GSM系统天线只由一个天线阵列构成。
如图3、4所示：8列单极化智能天线GSM单极化天线图38通道双极化智能天线GSM双极化天线图41.2.2〕功能区别智能天线可以通过改变各天线阵列的激励，利用波的干涉原理形成预定波束。
而GSM天线只有一个阵列，其波束在设计时已确定，出厂后不可改变。
2、智能天线的分类2.1、全向天线在360°任意方位上均可进行波束扫描的智能天线阵列。
2.2、定向单极化天线特指采用单极化辐射单元，组成定向阵列，可以在特定方向内进行波束扫描的天线阵列。
2.3、定向双极化天线特指采用双极化辐射单元，组成定向阵列，可以在特定方向内进行波束扫描的天线阵列。
2.4、未来发展前瞻总结一期试验网的经验，业内对智能天线提出了“四化〞的要求，即双极化、宽带化、小型化和电调化。
根据目前智能天线行业发展状况，双极化与小型化已经基本实现，并大量应用于二期建网中；宽带化与电调化也在紧锣密鼓的进行中，并且是未来发展的一个重要趋势，除此之外，rru一体化智能天线也是未来发展的一项重要技术。
详细分析如下：20##初，我国十城市TD-SCDMA试验网络开始建设，当时，智能天线产品只有单极化板状定向智能天线阵和环状全向智能天线阵两种可供选择。
虽然基本上能够满足TD-SCDMA网络实现动态空间滤波对智能天线的电气性能要求，但随着网络建设的深入，在工程实施方面遇到了诸多亟待解决的挑战：1〕天线横截面积大，导致风载荷增加、安全等级下降；2〕天线体积大，公众时有抵触情节，选址难度增加；3〕网络优化需要闭站，且天线下倾角调节难度大；4〕智能天线与城市景观不融洽、不和谐。

1. No visible mechanical damage
5. Soldering and Mounting
Mildly activated rosin fluxes are preferred. The minimum amount of solder can lead to damage from the stresses caused by the difference in
coefficients of expansion between solder, chip and substrate. The
terminations are suitable for all wave and re-flow soldering systems. If hand soldering cannot be avoided, the preferred technique is the utilization of hot air soldering tools.
Recommended temperature profiles for re-flow soldering in Figure 1.
Products attachment with a soldering iron is discouraged due to the inherent process control limitations. In the event that a soldering iron must be
employed the following precautions are recommended.
‧Preheat circuit and products to 150℃
‧Never contact the ceramic with the iron tip
‧Use a 20 watt soldering iron with tip diameter of 1.0mm
‧280℃ tip temperature (max)
‧1.0mm tip diameter (max)
‧Limit soldering time to 3 sec.
