Specification Part No : GPSF.36.7.A.30 Product Name : GPS L1/L2 36mm Single Feed Stacked Patch Passive Antenna Low AR Features : Highest Accuracy Low AR < 2.7 GPS Antenna GPS L1+L2 Band Operation Single Feed Patch Assembly L1:1575MHz; AR 1.69 @1575.42 MHz L2:1227MHz; AR 2.70 @1227.6MHz Dims: 36*36*7mm Tuned for Centre Positioning on a 70*70mm Ground-plane Through-Hole Mounting Pin Type RoHS Compliant SPE-17-08-027/A/WY Page 1 of 13 1. Introduction The GPSF.36.7.A.30 is a 36x36mm ceramic GPS L1/L2 low profile, low axial-ratio, embedded stacked passive patch antenna with a 7mm height. It is designed as a high performance yet economical solution for highest accuracy centimeter level tracking in telematics applications. Typical applicable industries are - UAVs and Drones - Transportation - Autonomous Vehicles - Marine - Agriculture - Navigation This compact antenna exhibits excellent gain and radiation pattern stability on both L1 and L2 bands, improved reliability of a GPS fix in urban areas, better signal reception with more satellites acquired, and a quicker time to first fix. The antenna has been tuned and tested on a 70 X 70 mm ground plane, working at GPS 1575.42 MHz and L2 1227.6MHz, with 5.44 dBi gain and 3.10 dBi gain, respectively. It can be easily through-hole mounted on PCB via pin. The double-sided adhesive on the bottom of the patch helps to keep it in place while being assembled. For further optimization to customer specific device environments, a custom tuned patch antenna and circuit integration service into your device can be supplied, subject to NRE and MOQ. Contact your regional Taoglas office for this requirement, and for support to integrate and test this antenna’s performance in your device. SPE-17-08-027/A/WY Page 2 of 13 2.
