Water-mediated dielectric antenna and model establishment method thereof

Abstract

The invention discloses a water-mediated dielectric antenna and a model establishment method thereof. The water-mediated dielectric antenna includes a water cooling and circulation structure, a supporting frame, an L-shaped probe, a grounding layer, a dielectric layer and a processor; water in the water cooling and circulation structure, replacing a metal layer in a traditional patch antenna, serves as a radiating medium; and air is adopted as a substrate, so that a wireless interface of any frequency to be achieved by changing the height of an air layer and changing the size of the water cooling and circulation structure. The invention also discloses a method for establishing the model of the dielectric antenna. According to the method, the model of the dielectric antenna can be established according to actual working requirements, so that the specific numerical values of the size parameters of the dielectric antenna can be obtained, and therefore, modeling and testing time before actual production can be saved.

Description

technical field [0001] The invention relates to a microstrip antenna, in particular to a dielectric antenna with water as a medium. Background technique [0002] The relative permittivity of water is around 81, and the greater the relative permittivity, the stronger its ability to bind electromagnetic fields. Traditional patch antennas such as figure 1 As shown, it includes a metal patch 101, a dielectric substrate 102, a ground layer 103, and a feeding probe 104. The dielectric substrate 102 is a filled dielectric material, and the metal patch 101 covering the dielectric substrate 102 serves as a radiation layer. Carry out wireless transmission and reception work; the traditional water dielectric antenna uses water to replace the filling material in the dielectric substrate 102, and its high dielectric constant can greatly reduce the size of the radiation patch, but using water as the filling material will seriously affect the Antenna transmit and receive efficiency.

[0003] At present, most of the desktop computer motherboards on the market do not have a card slot reserved for a wireless network card. If the computer needs to connect to a wireless device, an external wireless network card with a USB interface is required, which requires an additional USB interface; in addition, an external wireless network card There is a monopole antenna, which is bulky and not easy to carry
