Abstract

The low-profile dielectric antenna comprises a low-profile radiation patch structure, a middle-layer dielectric substrate and a bottom-layer dielectric substrate which are sequentially arranged from top to bottom, gap structures are arranged on the two opposite end faces of the low-profile radiation patch structure, silver coatings are arranged in the gap structures, and the silver coatings are arranged on the middle-layer dielectric substrate and the bottom-layer dielectric substrate. A metal bottom plate plane layer is arranged between the middle-layer dielectric substrate and the bottom-layer dielectric substrate, a linear coupling gap is formed in the middle of the metal bottom plate plane layer, a microstrip feeder line structure is arranged at the bottom of the bottom-layer dielectric substrate, the metal bottom plate plane layer and the microstrip feeder line structure form a feed structure, and the metal bottom plate plane layer is connected with the microstrip feeder line structure. The antenna has the characteristics of miniaturization, low power consumption and temperature stability.

Description

technical field [0001] The invention belongs to the technical field of antennas and relates to a low-profile dielectric antenna. Background technique [0002] In recent years, with the rapid development of fifth-generation (5G) mobile communication technology, 5G technology has now become the focus of a new round of technological competition in the global communication industry. This prompts the development of new passive microwave devices with high integration, high temperature stability and ultra-low power consumption to be paid more and more attention. Among them, one of the passive devices that promotes the development of 5G technology is the microwave antenna, which plays an important role in the terminal of the communication system. Therefore, in order to improve the performance of the antenna and reduce the size of the antenna, it is of great research and application value to design a high-performance dielectric material and a new antenna structure, which can obtain ...
