RF/Electrical Specifi cations
enable these antennas to provide a consistent, clear signal while minimizing
loss-of-lock even when GPS conditions are less than ideal. The 3961D comes
with a 45.2 mm diameter mini ground plane.

3961D Low Noise GPS Embedded Antenna
The 3961D Embedded GPS Antenna has one of the industry’s lowest noise fi g-
ures. It features a tuned custom ceramic patch element that minimizes detun-
ing effects caused by adjacent objects. It also features ESD circuit protection,
an innovative LNA (low noise amplifi er) and a high rejection SAW fi lter which
Features
• Comes with internal ground plane
• 15 KV ESD circuit protection
• Low noise fi gure: 0.5 dB
• Excellent out-of-band signal rejection
• Ideal for embedded applications
