Novel horizontal polarization omnidirectional dielectric resonator antenna

Abstract

The invention provides a novel horizontal polarization omnidirectional dielectric resonator antenna. The novel horizontal polarization omnidirectional dielectric resonator antenna is characterized in that two same dielectric circular rings and an excitation device disposed between the two same dielectric circular rings in a clamped manner are provided; the excitation device comprises arc-shaped monopoles, cone-shaped transition lines, and an impedance matching strip, which are disposed in a dielectric disc in an etched manner; the impedance matching strip is a circular area, which is formed by being etched and taking the circle center of the dielectric disc as a center; every cone-shaped transition line is electrically connected with the impedance matching strip, and is electrically connected with the corresponding arc-shaped monopole; the four cone-shaped transition lines are rotationally symmetric with respect to the center of the dielectric disc, and the four arc-shaped monopoles are rotationally symmetric with respect to the center of the dielectric disc. The novel horizontal polarization omnidirectional dielectric resonator antenna has advantages of simple excitation device, high omnidirectional performance, compact structure, and wide application in wireless communication system.

Description

technical field [0001] The invention belongs to the technical field of omnidirectional antennas, in particular to a horizontal linearly polarized omnidirectional dielectric resonant antenna, and the antenna has the characteristics of high horizontal plane omnidirectionality, simple excitation structure and compact overall size. Background technique [0002] Antennas can be divided into directional antennas and omnidirectional antennas according to their directivity. An omnidirectional antenna refers to an antenna that achieves 360° uniform radiation in the horizontal plane and a certain beam width in the vertical plane. The signal transmitted by the omnidirectional antenna can be received by the receiving end in any direction in the horizontal plane, and can receive signals in all directions of the horizontal plane at the same time. Omnidirectional antennas are generally used in wireless communication systems for large-area coverage, point-to-multipoint communication, such ...

AI Technical Summary

Problems solved by technology

Most of the commonly used horizontally polarized omnidirectional antennas are realized by similar current loop microstrip structures. In practical applications, the omnidirectionality of this type of antenna is poor in the horizontal plane, above 2dB

If the omnidirectionality of the horizontal plane is improved, the radiation and feeding structure of the antenna will be complicated, and the gain of the antenna in the horizontal plane will be reduced
