Antenna array element and millimeter wave antenna array of vertically integrated filter and communication device

The invention discloses an antenna array element of a vertically integrated filter. The antenna array element includes a dual polarized cavity filter and a dual polarized radiating element integratedon top of the dual polarized cavity filter; the dual polarized cavity filter is composed of a plurality of dual polarized resonance cavities which are connected in order from bottom to top, and a coupling window is arranged between the adjacent dual polarized resonance cavities. The invention also discloses a millimeter wave antenna array and a millimeter wave communication device. The element integrates the radiating element and the filter in a vertical direction, has the advantages of compact structure and small space occupation, and more importantly, ensures that the phases and amplitudes of signals transmitted by each array element in the antenna array are substantially the same. 本发明公开了一种垂直集成滤波器的天线阵元。该天线阵元包括双极化腔体滤波器和一体化集成于所述双极化腔体滤波器顶部的双极化辐射部件；所述双极化腔体滤波器由多个双极化谐振腔自下而上依次连接而成，相邻的双极化谐振腔之间设置有耦合窗。本发明还公开了一种毫米波天线阵列和一种毫
