Introduction The GWLA.10 GPS/GALILEO and 2.4/5.8GHz 2in1 Embedded Ceramic Loop antenna is a high efficiency, miniature SMD, edge mounted ceramic antenna for GPS/GALILEO and Wi-Fi, WLAN, ZigBee, Bluetooth, and 802.11ac applications where PCB space is limited, such as hand-held devices. Rather than using two separate chip antennas for GPS/GALILEO and Wi-Fi, the GWLA.10 has two separate antenna feeds in a single antenna body, making it the ideal choice for applications where there is limited PCB space and where low cost is important. The GWLA.10 uses the main PCB as its ground plane, thereby maintaining good efficiency despite its small size. This compact size antenna can be tuned for different PCB sizes/environments by changing the values of the matching circuit. This needs to be carefully calculated, contact a regional Taoglas facility for support. Also be aware that smaller ground-planes will reduce the efficiency of the antenna. 1. Introduction At 3.2*1.6*0.5mm, the GWLA.10 is one of the smallest antennas available worldwide. This antenna is delivered on tape and reel and manufactured in a TS16949 first tier automotive approved facility. 1. Introduction The GPS/GALILEO performance is excellent, with high efficiency and an omnidirectional pattern. The Wi-Fi performance is also great and delivers stable efficiency and radiation pattern too, allowing this antenna to be used in a huge variety of devices. Typical Applications – Where GPS/GALILEO and Dual-Band Wi-Fi are required Navigation or Position Tracking Systems Handheld Devices Tablets POS Systems Gateways and Routers Mobile Wireless Camera Systems OBD Devices SPE-16-8-049-D www.taoglas.com 3 Many module manufacturers specify peak gain limits for any antennas that are to be connected to that module. Those peak gain limits are based on free-space conditions. In practice, the peak gain of an antenna tested in free-space can degrade by at least 1 or 2 dB when put inside a device. So ideally you should go for a slightly higher peak gain antenna than mentioned on the module specification to compensate for this effect, giving you better performance. Upon testing of any of our antennas with your device and a selection of appropriate layout, integration technique, or cable, Taoglas can make sure any of our antennas' peak gain will be below the peak gain limits. Taoglas can then issue a specification and/or report for the selected antenna in your device that will clearly show it complying with the peak gain limits, so you can be assured you are meeting regulatory requirements for that module. For example, a module manufacturer may state that the antenna must have less than 2 dBi peak gain, but you do not need to select an embedded antenna that has a peak gain of less than 2 dBi in free-space. This will give you a less optimized solution. It is better to go for a slightly higher free-space peak gain of 3 dBi or more if available. Once that antenna gets integrated into your device, performance will degrade below this 2 dBi peak gain due to the effects of GND plane, surrounding components, and device housing. If you want to be absolutely sure, contact Taoglas and we will test. Choosing a Taoglas antenna with a higher peak gain than specified by the module manufacturer and enlisting our help will ensure you are getting the best performance possible without exceeding the peak gain limits. This antenna can be mounted with no performance degradation in either orientation as long as the antenna is soldered correctly via Surface mounting. Please see the integration instructions section for further detail regarding the optimum way to integrate this antenna into your device. For further optimization to customer-specific device environments and for support to integrate and test this antennas performance in your device, contact your regional Taoglas Customer Services Team.

Matching Circuit c Like all antennas, surrounding components, enclosures, and changes to the GND plane dimensions can alter performance. A pi-matching network like the one shown below is required incase adjustments need to be has a similar matching network. The components on the EVB are a good starting point 6.made. The antenna EVB5. for a new design, but will need to be adjusted upon integration for best performance. The zero ohm resistor is needed to solder down a coax pigtail to make measurements with a vector network analyzer. Packaging Mechanical Drawing 6. Packaging 7. Application Note6. Packaging5.
