Abstract

According to the reconfigurable antenna disclosed by the invention, a reconfigurable antenna scheme is realized by coupling a feed network, a power division module and three sub-antennas in different directions, and the antenna is simple in structure and high in portability; through the three mutually perpendicular monopole antennas, the polarization directions of the three sub antennas are mutually orthogonal, and through the spatial polarization reconstruction of the three orthogonal polarization antennas, the antenna can be suitable for implementing various polarization rotation, and the problem of polarization mismatching is reduced; the radiation direction and the polarization direction of the reconfigurable antenna are changed by changing the feed amplitudes of the three sub-antennas, so that the reconfiguration of the radiation direction and the polarization direction of the reconfigurable antenna is realized.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a reconfigurable antenna. Background technique [0002] With the development of communication technology, various user demands put forward higher requirements for wireless communication systems. Traditional single-function antennas restrict the improvement of system performance and cannot meet user needs. The reconfigurable antenna aims to change some parameters of the antenna so that the antenna can be reconfigured in real time according to actual needs. [0003] Reconfigurable antennas proposed in the prior art can be classified into frequency reconfigurable, pattern reconfigurable, polarization reconfigurable, etc. according to functions. However, the reconfigurable antenna provided by the prior art has a complex structure and poor portability. Contents of the invention [0004] In order to solve the above problems, the present invention proposes a reconfigur...
