Abstract

The invention discloses a dielectric resonant antenna. The dielectric resonant antenna comprises a filtering feed module and a dielectric resonator, wherein the dielectric resonator is arranged on thefiltering feed module in a stacked mode, the filtering feed module is used for feeding the dielectric resonator, the dielectric resonator includes a first dielectric block and a second dielectric block, and the second dielectric block is arranged in the first dielectric block in a penetrating mode. The dielectric resonant antenna disclosed by the invention can realize directional radiation in a 24.75-27.5 GHz frequency band, has advantages of s small loss, high radiation efficiency, s low profile, s small outline, s simple structure, easiness in processing and the like, and is very suitable for a 5G indoor communication system.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a dielectric resonant antenna. Background technique [0002] Modern communication has put forward higher and higher requirements for the miniaturization and low loss of the antenna. The traditional microstrip antenna has high metal loss in the high frequency band, and the antenna size is large in the low frequency band. Its development and application prospects are restricted. Certain restrictions. The dielectric resonant antenna is a kind of resonant antenna that has emerged in the past ten years. The radiating unit is composed of dielectric materials. Since the dielectric resonator is a pure dielectric structure and has no metal loss, the loss of the dielectric resonant antenna can be small and has high radiation. efficiency. At the same time, dielectric resonant antennas also have the advantages of easy miniaturization, broadband, multi-band, simple processing, and eas...
