Ceramic Patch Antenna
Model: PA Antenna
This microwave dielectric antenna elements and its series are designed to be used for GPS device. The patch antenna with compact size incorporates a rectangular micro-strip design for GPS C/A right-hand circular polarization wave reception, featuring low RL, low Axial Ratio but high gain, etc.
Pin length and outer diameter
Length: 1.6mm (Can depend on the customer demand change, the suggestion length1.9mm & 3.0mm)
Outer diameter: 0.8mm
