Problems solved by technology

However, in the millimeter wave band, more serious surface wave effects, higher dielectric loss and other unfavorable factors also bring troubles to the design of high-performance antennas
The usability of traditional transmission lines such as microstrip lines and striplines is greatly reduced, so there is a need to find transmission lines with good performance in the millimeter wave band

Abstract

The invention discloses an ultra-wideband single-layer slot array antenna based on a slot-gap waveguide, and relates to the technical field of millimeter-wave ultra-wideband antennas. The array antenna includes a metal base plate, the upper surface of the metal base plate is formed with a slot gap waveguide and a ridge gap waveguide, and the upper surface of the metal base plate other than the slot gap waveguide and the ridge gap waveguide is formed with several periodic A metal pin, the upper surface of the metal pin is covered with an upper metal plate, and several groups of U-shaped grooves are formed on the lower surface of the upper metal plate, and the size of the metal column corresponding to the U-shaped groove is smaller than that of the U-shaped The size of the metal pin on the outside of the slot. The array antenna has the advantages of ultra-wideband, simple structure, compact array unit, better loss performance than traditional microstrip devices, and the like.

Description

technical field [0001] The invention relates to the technical field of millimeter-wave ultra-wideband antennas, in particular to an ultra-wideband single-layer slot array antenna based on a slot-gap waveguide. Background technique [0002] In recent years, research on millimeter-wave antenna technology has attracted more and more attention. Millimeter-wave applications have the advantages of wide operating bandwidth, narrow beam width under a certain aperture, high resolution, less influence of climate on propagation, and easier miniaturization. However, in the millimeter wave band, adverse factors such as more serious surface wave effect and higher dielectric loss also bring trouble to the design of high-performance antennas. The availability of traditional transmission lines such as microstrip lines and striplines is greatly reduced, so there is a need to find transmission lines with good performance in the millimeter wave band. A new type of transmission line based on e...
