Abstract

The invention provides a liquid mixing chamber type regulable antenna. The liquid mixing chamber type regulable antenna comprises an antenna of a hollow cavity structure and a feed end connected with the antenna, wherein liquid is injected into the antenna; the feed end comprises a coaxial joint, a microwave dielectric substrate and metal ground arranged below the microwave dielectric substrate; the antenna is arranged above the microwave dielectric substrate; the coaxial joint is arranged by penetrating through the microwave dielectric substrate and the metal ground, the coaxial joint is provided with a probe communicated with the liquid inside the antenna, and the antenna comprises an inner cavity, an outer cavity and a regulation column; the inner cavity is arranged in the internal cavity of the outer cavity, and the regulation column is arranged by penetrating through the inner cavity and a through hole in the lower end of the outer cavity. The liquid mixing chamber type regulable antenna is simplified in structure, the inner cavity and the outer cavity can be communicated by pulling the regulation column, liquid heights in the inner cavity and the outer cavity are regulated, and changes of antenna pattern main lobe orientation and gain numerical value are caused, so that liquid distribution reconfiguration is realized, and radiation and matching performance of the antenna are changed.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a liquid mixing cavity type adjustable antenna. Background technique [0002] In the prior art, common wireless systems include radar, communication, navigation, etc., and their antennas are usually made of metal, or a mixed structure of metal and solid medium. Existing antennas mainly include two types: [0003] 1. Liquid metal antenna. The performance improvement and technical maturity of this antenna are highly dependent on the research and development of liquid metal materials, and its design method is close to that of conventional metal antennas. At present, the types and quantities of liquid metals at room temperature are limited, and they are still in the basic research stage. [0004] 2. Non-metallic antennas mainly use seawater, salt water, pure water or other organic and inorganic liquids as radiators, and design and realize antenna structures. After reviewing ...
