Abstract

The invention provides a high-gain millimeter-wave circularly polarized dielectric resonator array antenna for solving the technical problem of low gain of the existing millimeter-wave circularly polarized dielectric resonator array antenna, which comprises a dielectric substrate, a first metal floor printed on the upper surface of the dielectric substrate, and a second metal floor printed on thelower surface, wherein the first metal floor and the second metal floor are connected through a substrate integrated waveguide rectangular cavity; the substrate integrated waveguide feed structure iscomposed of a plurality of metallized through holes formed on the dielectric substrate; the area of the first metal floor located in the substrate integrated waveguide feed structure is divided into n*n feed units, wherein n is not smaller than 2; each feed unit is etched with a rectangular coupling slit, and a dielectric resonator antenna unit formed by stacking two dielectric blocks is fixed atthe position where the slit is located; and a through hole for mounting a coaxial line is formed on the dielectric substrate. The high-gain millimeter-wave circularly polarized dielectric resonator array antenna in the invention is applicable to a 5G millimeter wave communication system.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a high-gain circularly polarized dielectric resonator antenna, which is suitable for 5G millimeter wave communication systems. Background technique [0002] With the rapid development of modern wireless communication technology, especially the development of personal mobile communication technology, low-frequency wireless spectrum resources are gradually exhausted. In order to realize high-speed wireless access technology, it is necessary to develop high-frequency wireless spectrum resources. Due to its short wavelength and low interference, millimeter wave can effectively solve many problems faced by high-speed wireless access technology. Therefore, millimeter wave has become an important candidate frequency band for the next generation of mobile communications (5G) and future mobile communications. [0003] In order to break through the key technology of millimeter wave commu...
