Abstract

The invention discloses a dielectric resonator antenna and communication equipment. A dielectric layer is arranged on one side of a metal layer, a first dielectric block and a second dielectric block are arranged on the other side of the metal layer, and the metal layer is provided with two feed slots. The two dielectric blocks are excited by the two feed slots to radiate in different modes, so that the two feed slots and the first dielectric block or the second dielectric block form first mode resonance, the two feed slots and a rectangular space formed by the first dielectric block and the second dielectric block form second mode resonance, and the two feed slots form third mode resonance, so that three modes of resonance can be generated through the double slots and the two dielectric blocks, the frequency band coverage rate of an antenna module is greatly increased, and the structure of the antenna module is simplified by adopting a design mode based on a dielectric resonator antenna.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dielectric resonator antenna and communication equipment. Background technique [0002] 5G is the research and development focus of the global industry, and the development of 5G technology and the formulation of 5G standards have become the consensus of the industry. With the development of 5G technology, the requirements for 5G antenna modules are getting higher and higher. In particular, the performance requirements for covering multiple frequency bands are getting higher and higher. In order to realize that the 5G antenna module can cover multiple frequency bands, it is easy to think of using multiple antennas in different frequency bands to form a multi-antenna module. However, the multi-antenna module will inevitably increase the space occupied by the antenna device in the terminal device. [0003] In this regard, in the prior art, a design based on a broadband or mul...
