Abstract

The invention brings forward an open-ended ridge waveguide array antenna integrated with internal correction channels. According to the antenna, coaxial connectors arranged at the bottoms of open-ended waveguides are used for realizing feed; fundamental mode broadband conversion between the coaxial line and the ridge waveguide is realized by gradually-changed stair-stepping transition matching segments; rectangular open-ended waveguides with square ridges radiate electromagnetic waves to space; and the cross section dimensions of the open-ended waveguides are compressed fully to obtain two-dimensional wide-angle scanning features. Choke grooves are formed between adjacent antenna units; coupling grooves are arranged at the bottoms of the open-ended waveguides longitudinally to connect correction waveguides, thereby forming internal correction channels. One correction waveguide can be coupled with two adjacent columns of antenna units; and correction waveguide ridges and coaxial connectors are arranged in the correction waveguides to realize transmission and interfaces of the internal correction signals. Compare with the prior art, the antenna has advantages of broad band, two-dimensional wide-angle scanning , small size, low weight, and high reliability and integration and the like; and the internal correction function of a small-unit-space phased-array antenna is realized.

Description

technical field [0001] The present invention relates to the technical field of phased array antennas, in particular to an open ridge waveguide array antenna with an integrated internal correction channel, specifically a wide-band, two-dimensional wide-angle scanning, small volume, high integration and internal correction function planar array antenna. [0002] The invention can be used for transmitting and receiving radio waves, and has a wide range of application scenarios. In terms of military, it can be used as a terminal antenna of a phased array radar system with wide bandwidth sweep; in terms of civilian use, it can be used as a relay antenna for microwave communication. Background technique [0003] With the rapid development of phased array radar and communication systems, the performance requirements of phased array antennas are getting higher and higher. Especially for phased array radars based on airborne, UAV-borne, missile-borne and space-borne platforms, in a...
