Problems solved by technology

However, due to its high quality factor, the bandwidth of the antenna is still narrow
And because the radiation patch still has more surface wave loss at high frequencies, its gain is not high

Abstract

The invention discloses a parasitic patch array antenna with integrated waveguide feeding on a substrate, comprising a first dielectric board, a second dielectric board, a third dielectric board and a fourth dielectric board, wherein the first dielectric board is located on the second dielectric board Above, the second dielectric plate is located above the third dielectric plate, which is located above the fourth dielectric plate. A ring-shaped patch is arranged on the first dielectric plate, a main radiation patch is arranged on the second dielectric plate, and the metal through-hole structure on the third and fourth dielectric plates constitutes a four-substrate integrated waveguide feeding network , and feeds the main radiating patch through the gap on the third dielectric plate. The annular patch plays a guiding role, and the substrate integrated waveguide feeding network plays a role in reducing the feeding loss. The array antenna improves the shortcomings of large feed loss and low gain of the microstrip patch array antenna, and has the advantages of low profile, small volume, and easy integration of planar circuits, and can be used for low-profile terahertz or millimeter wave communications.

Description

Technical field: [0001] The invention relates to a parasitic patch array antenna with integrated waveguide feeding on a substrate, which belongs to the technical field of communication. Background technique: [0002] With the continuous development of communication information technology, in order to improve the communication rate of the communication system and alleviate the shortage of spectrum resources, more and more researches on the millimeter wave and terahertz frequency bands are conducted. Antennas are an important part of wireless communication systems. Working in high frequency bands requires antennas to have small size, high gain, high integration, and easy integration with planar circuits. [0003] The microstrip patch antenna has a planar circuit structure, is easy to integrate with microwave and millimeter wave circuits, and is easy to process and design, but the gain is not high, the bandwidth is narrow, and the high-frequency microstrip feed network has a la...
