88 tile-type satellite communication phased-array antenna subarray capable of performing arbitrary two-dimensional expansion

The invention relates to the field of satellite communication phased-array antennas, and discloses an 8 * 8 tile-type satellite communication phased-array antenna sub-array capable of any two-dimensional expansion, which comprises a first antenna layer, the first antenna layer is composed of 8 * 8 antenna units, the distance between two adjacent antenna units is half of the wavelength corresponding to the working center frequency of the antenna sub-array, and the distance between the two adjacent antenna units is half of the wavelength corresponding to the working center frequency of the antenna sub-array. And the length and the width of the antenna sub-array are four times of the wavelength corresponding to the working center frequency of the antenna sub-array. Compared with an antenna sub-array of a 1024 antenna unit which only supports 2 * N expansion at most, the antenna sub-array ruler in the invention can support any two-dimensional expansion in an N * N mode. 本发明涉及卫星通信相控阵天线领域，公开了一种可任意二维扩展的8×8瓦片式卫通相控阵天线
