Compact wideband, dual polarization and orientation diagram reconfigurable dielectric resonant antenna

Abstract

The invention discloses a compact wideband, dual polarization and orientation diagram reconfigurable dielectric resonant antenna and belongs to the technical field of antennas of wireless communication terminals. The antenna particularly comprises a dielectric resonant antenna body and a dielectric substrate. The dielectric resonant antenna body is fixed to the dielectric substrate. A metal floor is arranged on the upper surface of the dielectric substrate, and the lower surface of the dielectric substrate is corroded into a feed circuit. The left side and the right side of the dielectric substrate are each provided with an SMA coaxial port. Four holes penetrate through the upper surface and the interior of the dielectric substrate, copper needles are installed, and the dielectric resonant antenna body and the dielectric substrate are connected through the copper needles. The feed circuit comprises a feed coaxial line on the lower surface of the dielectric substrate, two coaxial ports and four feed ports. A dual-port equal-ratio power divider and an adjustable phase shifter are further included. The antenna is applied to the multi-user multi-input multi-output technology defined by a wireless local area network IEEE802.11ac protocol, and wideband, dual polarization and orientation diagram reconfigurable functions can be simultaneously achieved through the single antenna.

Description

technical field [0001] The invention belongs to the technical field of antennas for wireless communication terminals, and relates to a compact broadband dual-polarization azimuth pattern reconfigurable dielectric resonant antenna. Background technique [0002] At present, with the development of wireless communication technology and the rise of various communication standards, the functions of wireless communication products are becoming more and more complex and diverse, not only satisfied with: realizing broadband and dual polarization to support different frequency bands Communication standards must also meet the characteristics of simple production and low cost. In the recently drafted 5G standard, the multi-user multiple-input multiple-output technology (MU_MIMO) is proposed, which further requires the antenna to realize the functions of beamforming and multiple-input multiple-output (MIMO) at the same time, so as to meet the needs of serving multiple users at the same ...

AI Technical Summary

Problems solved by technology

[0005] At present, in order to realize the combination of beamforming technology and MIMO technology at the same time, the existing solutions use azimuth reconfigurable antennas with multiple units, or use dual-polarized phased antenna arrays to achieve; but these two solutions All solutions require the use of antenna arrays, resulting in a large antenna size; therefore, it is imminent to use a single antenna to realize broadband, dual polarization, and azimuth map reconfigurable functions at the same time.
