Problems solved by technology

[0004] This application provides a multi-layer microstrip antenna array element and antenna array surface, which is used to solve the problem of high production cost and large antenna loss when microstrip antennas in the prior art are increased in bandwidth by adding parasitic patches , the consequences of low gain, and the use of replacing the dielectric layer with an air layer to increase the bandwidth will easily cause a large deviation in the size of the air cavity, which seriously affects the technical problem of the wireless signal transmission and reception performance of the microstrip antenna.

Abstract

The invention discloses a multilayer microstrip antenna array element and an antenna array plane. A parasitic patch layer comprising a parasitic radiation patch and a first dielectric substrate is arranged, a foam dielectric layer comprising a foam dielectric sheet is arranged on one side of the parasitic patch layer, a radiation patch layer comprising a radiation patch and a second dielectric substrate is arranged on one side of the foam dielectric layer, and an antenna floor with a feed gap is arranged on one side of the radiation patch layer. And a feed network layer comprising a third dielectric substrate and a feed network is arranged on one side of the antenna floor. The foam dielectric sheet has the advantages of extremely low relative dielectric constant and loss tangent, transmission performance extremely beneficial to high-frequency application and the like, so the loss of the antenna can be reduced, the gain of the antenna can be improved, the production cost of the antennacannot be increased, and the production and processing are simple. The microstrip antenna has the technical effects of improving the bandwidth and the gain of the microstrip antenna, reducing the antenna loss and the production cost and ensuring the consistency of finished antennas.

Description

technical field [0001] The invention relates to the field of phased array antenna structures, in particular to a multilayer microstrip antenna array element and an antenna array surface. Background technique [0002] At present, microstrip patch antennas usually have a wide range of application requirements in the field of wireless communication due to their advantages of small size, light weight, low profile, and easy processing. However, the traditional microstrip antenna bandwidth is very narrow, generally only 1% to 7%. In order to achieve a wider bandwidth of the microstrip antenna, the following two methods are usually used in the prior art: the first is to add a layer of parasitic patch on the radiation patch of the traditional microstrip antenna, and the parasitic patch usually needs to be selected The loss tangent is very small for the plate, but this method will still increase the thickness of the entire microstrip antenna, increase the production cost of the micr...
