Dielectric resonator antennas and terminal equipment for millimeter waves

Abstract

This invention provides a dielectric resonator antenna for millimeter waves and a terminal device. The dielectric resonator antenna for millimeter waves includes a dielectric substrate, a metal ground plane, multiple dielectric resonator elements, and multiple feed lines. The dielectric substrate has a first surface and a second surface. A feeding structure is disposed on the dielectric substrate. The metal ground plane is attached to the first surface and has multiple feeding slots. The feed lines are disposed on the second surface. The first end of the feed line is connected to the feeding structure, and the second end of the feed line is used to couple the dielectric resonator elements. The dielectric resonator elements are disposed on the metal ground plane, and the multiple dielectric resonator elements are arranged in a line. The corners of the dielectric resonator elements have chamfers, and the chamfered surfaces are perpendicular to the metal ground plane. This antenna improves the isolation between dielectric resonator elements, reduces the coupling between dielectric resonator elements, and ensures a wider active bandwidth and a good radiation pattern.
