Problems solved by technology

The focal diameter ratio of the air-fed system is usually fixed, so the increase in the size of the mouth surface will increase the profile of the air-fed system, resulting in an increase in volume, and the huge volume will limit its popularization and application

Abstract

The invention relates to a low-profile novel phased array antenna based on a near-field air-feed mechanism, and belongs to the technical field of antennas. The antenna includes: a primary feed source, used to transmit or receive electromagnetic waves; a matching layer, used to adjust the electromagnetic waves emitted by the feed source, or converge the received electromagnetic waves into the primary feed source; a radiation layer, used to emit the electromagnetic waves from the matching layer Convert the electromagnetic waves into plane waves, or receive and remit the plane waves to the matching layer. The primary feed, the matching layer and the radiation layer are spatially cascaded in sequence and have a certain spatial distance. Compared with the traditional phased array antenna technology, the antenna of the invention has the characteristics of high integration, easy conformal shape, low profile and low cost.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to a low-profile transmission-type planar phased antenna based on a near-field coupling mechanism. Background technique [0002] High-gain beam-scanning antennas are very attractive and practical in wireless technologies, especially in systems such as 5G wireless communications, wireless power transfer, and satellite communications. The most representative high-gain beam scanning antenna is the traditional phased array antenna, which is composed of multiple radiating elements, multiple phase shifters and feeding networks. By changing the phase of each radiating element, a Focus beam. Due to its flexible beam scanning and beam agility functions, traditional phased array antennas are widely used. However, as the number of units increases, the complexity and loss of the feed network cannot be ignored in high-gain applications. In addition, the use of transceiver components also leads ...
