Abstract

The invention belongs to the technical field of antennas, and relates to a frequency polarization reconfigurable monopole antenna based on liquid metal, which comprises a dielectric substrate, a metal patch, a micro-flow tube substrate, a micro-flow pipeline, an injection port and liquid metal. According to the invention, the shape and the size of the antenna are changed by using the flowing characteristic of liquid metal at room temperature, and 50-time frequency polarization reconfiguration within 0.35-18GHz is realized. Liquid metal is used for controlling the length of the monopole antenna, frequency reconfiguration of the antenna is achieved, the liquid metal is used for changing current distribution of the monopole antenna floor, original linear polarization can be changed into circular polarization, and polarization reconfiguration is achieved. Compared with a traditional antenna, the liquid metal antenna can achieve continuous tuning, and the reconfigurable range is large; and secondly, the liquid metal has a relatively strong self-repairing characteristic, so that damage which is difficult to repair, such as fracture or bending, is basically avoided.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to a liquid metal-based frequency polarization reconfigurable monopole antenna and a reconfiguration method thereof, which uses the characteristics of liquid metal flowing at room temperature to change the shape and size of the antenna to achieve reconfigurability, satisfying A variety of environments require different requirements for the antenna operating frequency and polarization state. Background technique [0002] In the field of military electronics, future airborne platforms often require electronic systems to integrate multiple functions such as electronic reconnaissance, electronic jamming, radar detection, and wireless communication. This will also inevitably require the antenna to develop in the direction of ultra-wideband, multi-band, and multi-functional. At the same time, in terms of structural characteristics, the antenna is also required to have the characteristics ...
