Problems solved by technology

In 2012, Tam D.W. used the fluidity of liquid to design a dynamic seawater monopole antenna. The water column sprayed by the water pump is used as the monopole radiation structure of the antenna, but the performance of the antenna is affected by external factors such as the jet water column flow and wind force. Large, antenna stability needs to be improved

Abstract

The invention discloses a liquid patch antenna. The liquid patch antenna comprises a medium base plate which is provided with a metal floor, an exciting end port, a metal probe, a nonmetal radiation patch in which liquid is poured, and a nonmetal short circuit patch in which liquid is poured, wherein the nonmetal short circuit patch is vertically fixed to the metal floor; one end of the nonmetal short circuit patch is connected to the metal floor to form an earth short circuit, and the other end of the nonmetal short circuit patch is connected to the nonmetal radiation patch which is parallelto the metal floor; the nonmetal short circuit patch and the nonmetal radiation patch form an inverted L-shaped structure; liquid in the nonmetal short circuit patch is communicated with the liquid inthe nonmetal radiation patch; one end of the metal probe passes through the medium base plate and then extends into the nonmetal radiation patch, and the other end of the metal probe is equipped withthe exciting end port; and the metal probe is parallel with and close to the nonmetal short circuit patch without direct contact. The liquid patch antenna has the characteristics of being high in radiation efficiency, high in gain, high in impedance bandwidth and universal radiation, and the working frequency ranges from 2.26-3.24GHz.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a liquid patch antenna. Background technique [0002] With the development of communication technology, the requirements for various performances of antennas in communication applications are getting higher and higher. People hope that the size of the antenna should be small, the radiation efficiency should be high, the gain should be high, the bandwidth should be wide, and the omniphase performance should be good. The traditional antenna structure is gradually difficult to meet these requirements, prompting researchers to continuously explore the application of new materials and technologies in antenna technology. Liquid antennas are an important research direction for the application of new materials in antenna technology. [0003] Traditional antennas, especially patch antennas, mainly use metal as the radiation structure, and the idea of ​​liquid antennas is to replace the solid metal...
