Abstract

The invention discloses an integrated substrate chamber millimeter wave array antenna. The antenna comprises an antenna array, a power division module and an external switching module, wherein the external switching module is used for leading electromagnetic waves from metal waveguide to the power division module, the electromagnetic waves are divided by the power division module into multiple paths of electromagnetic waves for output, the electromagnetic waves enter into an integrated substrate chamber of an antenna unit, high-order mode resonance is generated in the integrated substrate chamber through expanding a radiation aperture of the integrated substrate chamber, gain of the millimeter wave array antenna is improved, high-order mode field distribution of the electromagnetic waves in the integrated substrate chamber is adjusted through a parasitic structure, so the high-order mode radiation direction of the electromagnetic waves in the integrated substrate chamber is turned to be in a normal direction of the integrated substrate chamber, and normal operation of the antenna array is realized, moreover, the parasitic structure employs an I-like metal sheet, current length of the metal sheet can be improved, and bandwidth of the antenna array is enhanced.

Description

technical field [0001] The invention belongs to the technical field of millimeter-wave antennas, and in particular relates to a substrate-integrated cavity millimeter-wave array antenna. Background technique [0002] With the continuous development of communication technology, the spectrum resources of traditional microwave frequency bands are increasingly tight. In order to alleviate this problem, people have gradually shifted their attention to the millimeter wave frequency band with a higher frequency band. Millimeter wave has attracted extensive attention due to its short wavelength, wide frequency bandwidth, and fast transmission rate. In a wireless communication system, the transmission and reception of the radio must rely on the antenna. As a key component in the millimeter wave communication system, the millimeter wave antenna has a crucial impact on the final performance of the system. However, since the millimeter wave has a large attenuation when propagating in...
