GCA02: High Gain GNSS L1 Active Patch Antenna


The EXA GCA02 is a two-stage, 33dB gain compact GNSS active patch antenna solution than works with your GNSS card and link it to GPS and GALILEO constellations in the L1 band, It is the ideal antenna for space-grade GNSS devices to achieve good sensitivity across all bands in a small form factor.

The active patch antenna, by means of a double resonance design, has a wide-band operation over GPS/GALILEO systems from 1575.42MHz L1 band. It includes a one-stage LNA and front-end SAW filter to reduce out of band noise; this antenna offers better protection from LEO radiation and greatly reduces the probability of damaging your GNSS receiver due to nearby transmissions.
