The invention provides a waveguide slot array antenna and communication equipment, and belongs to the technical field of antennas. The waveguide slot array antenna comprises a feed network, an impedance conversion network and an antenna array surface, wherein the antenna array surface is provided with a plurality of antenna subarrays; the antenna subarray comprises a waveguide, a first metal ridge and a plurality of inductive diaphragms, and the upper surface of the waveguide is provided with a radiation slot unit; the first metal ridge is fixedly connected with the lower surface of the waveguide and extends upwards; the plurality of inductive diaphragms are arranged at two sides of the waveguide; and the inductive diaphragms are symmetrically arranged about the axis of the waveguide along the extension direction of the waveguide. According to the waveguide slot array antenna, the inductive diaphragms are arranged on the two sides of the waveguide of the antenna subarray, and the dispersion effect can be eliminated through loading of the inductive diaphragms, so that the sidelobe level is reduced, and the waveguide slot array antenna can be machined more accurately in the millimeter wave frequency band.
Description
technical field [0001] The invention relates to the technical field of antennas, in particular to a waveguide slot array antenna and communication equipment. Background technique [0002] The waveguide slot array antenna refers to the antenna that cuts a narrow slit on the waveguide wall according to certain rules to generate electromagnetic wave radiation. At the same time, with the rapid development of electronic science and technology, waveguide slot array antennas have advantages that other types of antennas cannot match, such as compact structure, high aperture efficiency, large power capacity and low loss, so this type of antenna has received extensive attention and research. . [0003] The waveguide slot array antenna can be used to form a fan-shaped beam antenna. The fan-shaped beam antenna has different directivity and beam width characteristics on the two main planes. It is used in wireless communication, medical imaging, mobile communication base stations, indoor...
