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 slot gap waveguide, and relates to the technical field of millimeter wave ultra-wideband antennas. The array antenna comprises a metal bottom plate, a slot gap waveguide and a ridge gap waveguide are formed on the upper surface of the metal bottom plate, a plurality of periodic metal pins are formed on the upper surface of the metal bottom plate except the slot gap waveguide and the ridge gap waveguide, the upper surface of each metal pin is covered with an upper metal plate, a plurality of sets of U-shaped grooves are formed in the lower surface of the upper-layer metal plate, and the size of the metal columns corresponding to the U-shaped grooves is smaller than that of the metal pins on the outer sides of the U-shaped grooves. The array antenna has the advantages of ultra wide band, simple structure, compact array unit, better loss performance than a conventional microstrip device 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 mmWave antenna technology has attracted increasing attention. Millimeter-wave applications have the advantages of wide operating bandwidth, narrow beamwidth at a certain aperture, high resolution, less climate impact on propagation, and easier miniaturization. However, in the millimeter wave band, unfavorable factors such as more serious surface wave effects and higher dielectric loss 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. A new type of transmission line based on electromagnetic band...
