Multifunctional radio frequency device based on dual-polarization magnetoelectric dipole

Abstract

The invention discloses a multifunctional radio frequency device based on a dual-polarization magnetoelectric dipole, which comprises a dual-polarization symmetric array radiation structure, a feedingnetwork structure and a reflection plate. The dual-polarization symmetric array radiation structure comprises two mutually orthogonal vertical substrates, three mutually perpendicular metal plates are arranged in each region formed by two mutually orthogonal vertical substrates, wherein two metal plates are vertically arranged on the reflective plate and the other metal plate is horizontally arranged above the two metal plates perpendicular to the reflective plate. The feeding network structure comprises an r-type feeder loaded with parasitic hook-shaped self-coupling lines, one branch of ther-type feeder is loaded with hook-shaped self-coupling lines, and the hook-shaped self-coupling lines are arranged on the vertical substrates. The invention does not need to change the circuit structure additionally, can control the filter and the antenna channel separately, and realizes the dual-port multifunctional radio frequency device.

Description

technical field [0001] The invention relates to the field of wireless mobile communication, in particular to a multifunctional radio frequency device based on a double-polarized magnetoelectric dipole. Background technique [0002] my country's microwave communication widely uses L, S, C, and X frequency bands, and the application of K frequency band is still under development. Since the frequency of microwave is extremely high and the wavelength is very short, its propagation characteristics in the air are similar to light waves, that is, it moves in a straight line and is reflected or blocked when encountering obstacles. Therefore, the main way of microwave communication is line-of-sight communication. Relay forwarding is required after the line of sight. The equipment of the microwave station includes antennas, transceivers, modulators, multiplexing equipment, power supply equipment, and automatic control equipment. Compared with traditional single-function devices, mul...

However, all of these designs only provide the functionality of a single component, i.e. filter or antenna

[0004] At this stage, devices with multifunctional microwave components or programmable microwave components have also been developed. By using dual-function cavity resonators in the prior art, a two-in-one design of filter and antenna integration is proposed to realize three different frequency bands Although the filtering and radiation operation of the dual-polarization function is realized, the bandwidth is only 0.33%; in addition, the patch or dielectric resonator is used as the radiator and filter of the same frequency, and the radiator only has a single-polarization application; and in In these designs, the filter and antenna share a resonator, so their center frequency or bandwidth cannot be tuned independently
