Problems solved by technology

[0004] However, when the microstrip antenna is integrated into an integrated circuit, there will be electromagnetic compatibility problems, which will reduce the quality of communication. Therefore, it is necessary to add a filtering structure to suppress harmonics, but the general filtering structure may cause problems in the frequency reconfigurable When the antenna works at a low frequency, the filter structure to remove low frequency harmonics may cause the antenna to fail to work properly when it switches to a high frequency working state

Abstract

The invention relates to a dual-polarized three-band frequency reconfigurable antenna with a reconfigurable harmonic suppression function, comprising an upper dielectric substrate and a lower dielectric substrate, a reconfigurable radiation unit for the upper antenna, and a reconfigurable radiation unit for the lower antenna , the upper layer reconfigurable filter structure, the lower layer reconfigurable filter structure, realize the reconfigurable frequency of the three frequency bands and the reconfigurable antenna polarization, and also realize the harmonic of each frequency band when the antenna works in different frequency bands The arrival of the wave is suppressed without affecting the normal work of other frequency bands.

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...
