Problems solved by technology

Compared with solid antennas, liquid gallium-indium alloy antennas have properties such as fluidity, high dielectric constant, good wettability, high conductivity, low volatility, and non-toxicity. These properties provide safety for the production of liquid gallium-indium alloy antennas. Guaranteed, and these properties of liquid gallium indium alloy fully meet the indicators for selecting materials when making antennas. However, the existing reconfigurable antennas are all solid-state antennas, and there are few studies on the reconfigurability of liquid metal antennas. Therefore, how to reconfigure the liquid metal antenna is still a problem that needs to be continuously solved and improved.

Abstract

The invention discloses a reconfigurable antenna element based on a liquid gallium-indium alloy and a reconfigurable antenna. The reconfigurable antenna element comprises a hollow housing and a liquidgallium-indium alloy column in the hollow housing, wherein the hollow housing is provided with a plurality of solution reservoirs and a plurality of adsorbent reservoirs symmetrically distributed with the solution reservoirs; one end of each solution reservoir and one end of each adsorbent reservoir pass through the hollow housing and are in contact with the liquid gallium-indium alloy column; the solution reservoirs selectively contain a NaOH solution or a H2O2 solution; and the adsorbent reservoirs contain a solution adsorbent. The reconfigurable antenna, by the chemical reaction of the solution in the solution reservoirs and the liquid gallium-indium alloy column, changes the effective length of the reconfigurable antenna element and adjusts the structure of the antenna so as to make the antenna compatible with different resonant frequencies and expand the bandwidth of the antenna.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a reconfigurable antenna vibrator and a reconfigurable antenna based on liquid gallium indium alloy. Background technique [0002] Reconfigurable antennas (Reconfigurable Antenna) can generally be divided into three types: frequency reconfigurable antennas, pattern reconfigurable antennas, and polarization reconfigurable antennas. Among them, frequency reconfigurable antennas maintain the antenna pattern Under the premise that the polarization mode remains unchanged, the resonant frequency is changed by adjusting the effective electrical length of the antenna, so that it has the ability to change the frequency. The current reconfigurable antennas are mainly solid-state antennas, and the design focuses on using RF PIN, diodes, varactor diodes and other switch designs to adjust the structure of the antenna to complete the reconfigurability of the frequency, polarizatio...
