Problems solved by technology

[0003] 1) Large size, heavy weight, difficult to move
[0004] 2) The material cost is high, the processing cost is expensive, and the related mechanical cost increases due to its difficulty in moving
[0005] 3) The manufacturing accuracy cannot guarantee the normal operation of the antenna, so after the processing is completed, an adjustment process is required to correct the error
These defects make this type of antenna very expensive

Abstract

This invention discloses a dielectric substrate integrated waveguide slit array antenna used in radio communication, radar, electronic navigation and ECM etc including a dielectric substrate board with metallic foils on the positive and negative sides, a slit array and a microstrip power splitter are connected and etched on one side of the metallic foil set with inter-connected metallized through holes queued in 'U' enclosing the slit array.

Description

technical field [0001] The invention relates to an antenna that can be used in antennas and feed modules of communication systems, in particular to a dielectric substrate integrated waveguide slot array antenna. Background technique [0002] The traditional metal waveguide slot array antenna has excellent characteristics such as narrow main lobe width, shapeable pattern, and low cross-polarization level, and is widely used in microwave and millimeter wave radar and communication systems. A complete metal waveguide slot array antenna system is composed of multiple metal waveguides, some of which are slotted on the wall to form a slot array, and the other part of the waveguide is used as a feed network. This inevitably has some drawbacks: [0003] 1) It is bulky, heavy and difficult to move. [0004] 2) The material cost is high, the processing cost is expensive, and the related mechanical cost increases due to the difficulty in moving it. [0005] ...
