一种ka和k波段双频双极化宽带宽角扫描共口径天线单元及天线阵列
By using a multi-layer printed circuit board structure for Ka and K band dual-frequency dual-polarization common aperture antenna elements, combined with a low-frequency L-shaped probe-coupled microstrip patch and a high-frequency shielded frame slot antenna, the isolation and bandwidth issues of the common aperture antenna array are solved, achieving wide-angle scanning and high isolation, thus meeting the broadband requirements of communication systems.
