Abstract

The invention provides a liquid metal antenna and a control system and method thereof. The liquid metal antenna comprises an antenna body, the antenna body comprises a substrate, a first elastic layer and a feed port, the first elastic layer is fixedly installed on the substrate, a filling cavity is formed between the first elastic layer and the substrate, one end of the feed port is communicated with the filling cavity, the lower part of the substrate is provided with a discharge structure, and one end of the discharge structure is communicated with the filling cavity. Through large-scale deformation of the first elastic layer, the first elastic layer can be attached to the wall surface and the corner of the filling cavity, so that the liquid metal in the filling cavity can be completely discharged, the residual rate of the liquid metal is reduced, an acidic or alkaline solution does not need to be used, stable control of the antenna is realized, and the antenna can work stably.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a liquid metal antenna and its control system and method. Background technique [0002] Due to the high conductivity and fluidity of liquid metal, the liquid metal antenna made of liquid metal will not bring much loss and nonlinear problems compared with traditional antennas. By controlling the antenna cavity The liquid metal flow can realize the control of the liquid metal antenna. [0003] However, liquid metal is easily oxidized, and the conductivity of the oxidized liquid metal will decrease, which will lead to a decrease in the performance of the antenna, and the adhesion of the oxidized liquid metal will be enhanced. In the process of controlling the flow of liquid metal, the liquid metal And its oxide is easy to adhere to the cavity of the antenna, resulting in a high residual rate of liquid metal. [0004] In view of the above-mentioned problem that liquid metals are e...
