Abstract: This paper proposes a large-spacing scanning phased array based on U-slot patch antennas. A genetic algorithm is used to optimize the beamforming for a $1 \times 5$ subarray. And taking into ...
Abstract: A 3-D wideband high-gain circularly polarized array antenna with low radar cross section (RCS) is presented in this letter. Its element contains four 3-D radiation structures fed by a ...
