S Conception, Realization, Evaluation of a Seven-Element GNSS CRPA A controlled radiated pattern antenna can be an effective way to protect GPS receivers against jamming. A new CRPA, composed of seven elements, functions in the E5a, E5b, E6, L2, and L1 bandwidths. Follow the link below to read the report on radiation pattern measurements of the array in a test facility: GPSWorld: http://gpsworld.com/anti-jam-protection-by-antenna/

The antennas presented above are dedicated to GNSS receivers used for land, aerospace and maritime applications. These antennas are either FRPA (Fixed Radiation Pattern Antenna) consisting of a single patch antenna or CRPA (Controlled Radiation Pattern Antenna) consisting of several patch antennas combined to protect GNSS receivers against jamming.
