Description

technical field

[0001] The invention belongs to the technical field of antennas, and relates to a dual-polarization and three-band frequency reconfigurable antenna with a reconfigurable harmonic suppression function, which can be applied to a wireless communication system. Background technique

[0002] Since the 1960s, with the rapid development of modern radar and communication systems, the number of antennas required for aircraft, ships, satellites, etc. many. As a result, the weight of the platform continues to increase, and the cost of building the antennas also continues to rise. At the same time, the electromagnetic interference between the antennas is also very large, which seriously affects the normal operation of the antennas. Due to the small size and changeable functions of the reconfigurable antenna, in order to reduce the weight of the antenna loaded on the platform and reduce the cost, research institutions at home and abroad have conducted some in-depth resea...
