Problems solved by technology

Most of the existing beam scanning antennas are designed based on microstrip patch antennas. However, the impedance bandwidth of this antenna is very narrow, which cannot meet the broadband requirements of today's wireless communication systems. At the same time, the gain of this antenna is not high enough to be able to Meet the needs of long-distance transmission of electromagnetic signals

Abstract

The invention discloses a magnetoelectric dipole reconfigurable antenna and a wireless communication system. The magnetoelectric dipole reconfigurable antenna comprises a first dielectric substrate, a plurality of groups of magnetoelectric dipole antenna units mounted on the first dielectric substrate, a reconfigurable feed network and a plurality of adjustable feed branches, wherein the reconfigurable feed network and the plurality of adjustable feed branches are arranged on the first dielectric substrate, the reconfigurable feed network comprises a T-shaped power divider and a plurality of reconfigurable phase shifters, wherein the T-shaped power divider is electrically connected with the plurality of reconfigurable phase shifters through a controllable switch, the plurality of adjustable feed branches are electrically connected with the plurality of groups of magnetoelectric dipole antenna units in a one-to-one correspondence manner, the plurality of adjustable feed branches are also electrically connected with the T-shaped power divider of the reconfigurable feed network through a direct-current feed line; and when the controllable switch is switched on, the corresponding adjustable feed branch and the reconfigurable phase shifter are sequentially communicated with the T-shaped power divider, so that the excitation phases of the magnetoelectric dipole antenna units are adjusted. According to the magnetoelectric dipole reconfigurable antenna and the wireless communication system of the invention, the magnetoelectric dipole antenna has a wave velocity scanning function.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a magnetoelectric dipole reconfigurable antenna and a wireless communication system. Background technique [0002] With the rapid development of wireless communication technology, the role of antennas in communication systems is becoming more and more important. In recent years, beam-scanning antennas have received extensive attention due to their advantages of increasing signal coverage. Most of the existing beam scanning antennas are designed based on microstrip patch antennas. However, the impedance bandwidth of this antenna is very narrow, which cannot meet the broadband requirements of today's wireless communication systems. At the same time, the gain of this antenna is not high enough to be able to Meet the needs of long-distance transmission of electromagnetic signals. Contents of the invention [0003] The main purpose of the present invention is to propos...
