Abstract

The invention discloses a waveguide aperture antenna which comprises a plurality of substrate-integrated waveguide aperture sub-arrays based on H-plane Taylor distribution, one or more feed networks and a metal cylinder, wherein the waveguide aperture sub-arrays form an ultralow minor lobe directional diagram on the waveguide aperture antenna H plane; the feed networks are correspondingly connected with the waveguide aperture sub-arrays and are used for feeding signals with unequal power and different phases into the connected waveguide aperture sub-arrays respectively and controlling a waveguide aperture antenna E-plane array to form an E-plane Taylor distribution array of an E-plane ultralow minor lobe directional diagram; and the waveguide aperture sub-arrays and the feed networks are connected on the circumference of the metal cylinder by surrounding. The waveguide aperture antenna solves the problem that anti-interference capability and working efficiency of a conformal substrate-integrated waveguide aperture antenna cannot meet higher requirements in the prior art.

Description

technical field [0001] The present invention relates to the technical field of waveguide slot antennas, and more specifically relates to a waveguide slot antenna and a wireless communication system. Background technique [0002] Modern communication, radar and other electronic systems are rapidly developing towards miniaturization, light weight, low cost, easy conformality, high integration and high performance. In order to meet the above needs, low-cost, high-performance and Highly integrated conformal antenna and waveguide slot antenna. [0003] Among them, the conformal antenna is an antenna or array that conforms to a surface of a specified shape, and the shape of the surface is determined by factors such as aerodynamic or hydraulic forces; the waveguide slot antenna is cut according to certain rules on the waveguide wall Narrow slots, antennas that generate electromagnetic radiation. [0004] In order to meet higher requirements, waveguide slot antennas in the prior a...
