Broadband two-dimensional beam scanning dielectric resonant antenna and wireless communication system

Abstract

The invention provides a broadband two-dimensional beam scanning dielectric resonant antenna and a wireless communication system. The antenna comprises a first dielectric resonator, a second dielectric resonator, a third dielectric resonator, a dielectric substrate, a feed line and a ground plate. The feed line and the ground plate are arranged on both sides of the dielectric substrate. The groundplate is provided with at least two intersecting rectangular slits. The feed line is centered on the intersection of at least two intersecting rectangular slits, and is arranged on one side, which isaway from the ground plate, of the dielectric substrate in a circular arc shape. The first dielectric resonator is arranged between the ground plate and the second dielectric resonator. The second dielectric resonator is arranged between the first dielectric resonator and the third dielectric resonator. The center of the first dielectric resonator, the center of the second dielectric resonator and the center of the third dielectric resonator are in line with the circle center. The feed of the feed line is coupled to the ground plate by the slits and excited, so that the third dielectric resonator rotates to achieve beam scanning. A receiving end can receive a signal.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a broadband two-dimensional beam scanning dielectric resonant antenna and a wireless communication system. Background technique [0002] With the rapid development of wireless communication technology, electronic devices with wireless communication functions have become a necessity in people's lives. People rely more and more on electronic devices, and at the same time, the requirements for transmission efficiency of wireless communication are also getting higher and higher. [0003] As a resonant antenna, the dielectric resonator has many advantages. For example, the dielectric resonator can be designed in a variety of forms and has great flexibility; the feeding methods include probes, slot coupling, microstrip lines, etc.; and for example , the radiating unit of the dielectric resonator is a pure dielectric material, and the selection range of the dielectric con...
