Abstract

The high-gain waveguide horn array panel antenna comprises: from top to bottom, a top conductive plate with multiple horn holes arranged feeding through hole on bottom on top surface and multiple cavity guide pipes on lower surface, a middle conductive plate with waveguide hole opposite to these in cavity, a thin cable-layer conductive plate, and a bottom conductive plate. This invention can achieve higher precision, reduces weight and cost, and fit wide application.

Description

technical field [0001] The invention relates to the field of panel antenna technology, and is a high-gain waveguide horn array panel antenna Background technique [0002] At present, there are mainly two types of common panel antennas, microstrip antennas and waveguide antennas. The microstrip antenna has the characteristics of small size and light weight. However, due to the characteristics of the dielectric plate in the microwave frequency band, the loss of the final antenna is large and the bandwidth is narrow. Therefore, the manufacture of a high-gain microstrip antenna has many difficulties such as large area and high cost. [0003] The waveguide antenna mainly uses slots or horns as the radiation unit of the antenna. Since the antenna does not use dielectric materials, the loss caused by it is avoided, so it is easy to manufacture high-gain antennas. However, the waveguide antenna also has the disadvantages of large volume and difficult processing, which is not conduc...
