Microwave beam pattern antenna
Web8 apr. 2024 · Controlled Reception Pattern Antennas or CPRA are adaptive beam steering antennas whose reception pattern can be adjusted to create nulls in the direction of interfering signals. They create a sort of spatial filter that eliminates signals from a particular direction while letting through signals from other directions. WebANTENNA ARRAYS AND BEAMFORMING Array beam forming techniques exist that can yield multiple, simultaneously available beams. The beams can be made to have high gain and low sidelobes, or controlled beamwidth. Adaptive beam forming techniques dynamically adjust the array pattern to optimize some characteristic of the received signal.
