Abstract

The invention discloses a polarized reconfigurable antenna. The polarized reconfigurable antenna comprises a dielectric substrate (1), an upper metal layer (21), a lower metal layer (22), a pair of controllable grounding through holes (5) with symmetrical structures, and more than two metal through holes (41) in array configuration to form a cavity body (4); the upper metal layer (21) is provided with an antenna radiation structure while the lower metal layer (22) is provided with an antenna feed structure; the grounding through holes (5) are connected with a switch separately; and the switch is used for controlling the grounding states of the grounding through holes (5) to realize different current disturbances. By changing the switch state, namely, changing the states of the pair of controllable grounding through holes, current disturbances are changed to form three kinds of different polarized waves, including linear polarization wave, left-hand circular polarization wave and right-hand circular polarization wave, thereby realizing the polarized reconfigurable antenna.

Description

technical field [0001] The invention belongs to antenna technology, in particular to a polarization reconfigurable antenna. Background technique [0002] The rapid development of wireless communication technology has put forward higher requirements for system requirements and working modes. The traditional single-function antenna cannot meet the current needs well, and has become a bottleneck restricting the development of system performance. The proposal and development of reconfigurable antennas provide a good solution to these problems. Polarization reconfigurable antennas can increase the capacity of the system through frequency multiplexing, and can solve the problem of polarization mismatch in communication, thereby improving the quality of communication. [0003] Since the modern single-layer PCB technology is very mature, the processing accuracy is also guaranteed in the not very high frequency band. At the same time, the processed products can have the characterist...
