## **1. Introduction** 

The Taoglas GWSFTP.50.3.A.08 is a 50*50mm Terrablast GPS & Wi-Fi embedded stacked passive patch antenna with 3mm thickness. This low profile patch is made from a revolutionary new material developed to meet the unique needs of the UAV and automotive industries. It uses a patent pending antenna technology which results in lighter weight patches, up to 35%, with mush greater impact resistance. 

Typical applicable industries are: 

:: Transportation :: Defense :: Marine :: Agriculture :: UAV Navigation 

The antenna has been tuned and tested on a 70*70mm ground plane and works at GPS (1575.42MHz) and Wi-Fi (2.4Ghz) bands. The GWSFTP.50 is mounted via a pin and double sided adhesive. This antenna works well without modifications in most environment but can be tuned and further optimized to different ground planes and enclosures if this is required. Custom antenna modifications are subject to possible NRE and minimum order quantity. 

Terrablast antennas are not suitable for SMD reflow. The correct method is manual soldering at a soldering temperature of 380°C +/- 20°C for a duration of 3 to 5 seconds. All Terrablast antennas undergo rigorous temperature, vibration and impact tests and exceed the highest ISO16750 standards.
