Description

technical field [0001] The invention relates to the field of antenna equipment, in particular to a broadband dual-polarized solar cell antenna and an antenna array. Background technique [0002] At present, solar cells are widely used in solar power stations, roof power generation arrays, solar street lights, solar aircraft, ships, automobiles, etc. as light energy to electrical energy conversion devices. As an electromagnetic transceiver device, antennas are widely used in various communication equipment, electromagnetic detection equipment, etc. Both the array antenna and the solar cell need a certain aperture area to provide effective gain and collect sunlight. The solar cell and the antenna array are integrated to design a new device with the functions of the antenna and the solar cell. Moreover, the solar cell generates electricity It can be distributed and directly used by the antenna system. Compared with the external centralized power supply, the power supply line i...
