Reconfigurable antenna and manufacturing method therefor

Abstract

The invention relates to a reconfigurable antenna and a manufacturing method therefor, and mainly aims to solve the problems of small tuning range, single re-configurability and high loss of the reconfigurable antenna in the prior art. A technical scheme is adopted as follows: the reconfigurable antenna comprises a source antenna layer, a metal ring structural layer and a metal cut corner structural layer arranged from the bottom up; the source antenna layer adopts a slit microstrip antenna structure, and comprises a floor with rectangular coupling slits and a dielectric plate with rectangularmetal radiation patches; the metal ring structural layer comprises rectangular metal ring units periodically arranged in the directions of X axis and Y axis; the metal cut corner structural layer comprises square metal cut corner units periodically arranged in the directions of X axis and Y axis; the metal ring structural layer performs clockwise rotation to form an included angle <theta>1 with the X axis; and the metal cut corner structural layer performs clockwise rotation to form an included angle <theta>2 with the X axis. By virtue of the method, the problems are well solved, and the reconfigurable antenna can be used for an intelligent communication system.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a reconfigurable antenna related to polarization and frequency. Background technique [0002] In recent years, polarization reconfigurable antennas are especially suitable for mobile terminals with limited volume because they can add independent transmit and receive channels without increasing the antenna volume. At the same time, the multipath fading effect of radio signals has a serious impact on the communication quality of many wireless communication systems. The use of polarization reconfigurable antennas can not only eliminate multipath fading effects, but also increase frequency reuse, so polarization reconfigurable antennas It has become a hotspot in the research of reconfigurable antennas. Generally speaking, polarization reconfigurable antennas are mostly realized through electronic tuning technology. By increasing the low-frequency bias voltage and controlling the bi...
