A Low Profile Magnetoelectric Dipole Folded Antenna

Abstract

The invention provides a low-profile magnetoelectric dipole folded antenna, which includes from top to bottom: a rectangular frame surrounded by vertical metal baffles, inside the rectangular frame from top to bottom are sequentially arranged two horizontal rectangular metal patches, two A folded vertical metal patch, a metal floor, the metal ground has two protrusions under the folded vertical metal patch, each protrusion has a gap on the bottom surface, the antenna feed part includes an SMA connector and a metal strip feeder, The invention effectively prolongs the magnetic dipole current path by simultaneously folding the vertical metal patch and the metal floor located in the middle of the vertical patch, and can reduce the antenna profile from 0.25λ to 0.075λ. While maintaining the height of the electric dipole antenna, it retains its advantages of wide impedance bandwidth, symmetric pattern, high radiation gain and small back radiation, so that the profile height is no longer a defect in the application of all-metal magnetoelectric dipole antennas. It can be applied to 5G base station antenna system.

Description

technical field [0001] The invention belongs to the technical field of 5G base station antennas, in particular to a low-profile magnetoelectric dipole folded antenna. Background technique [0002] The rapid development of mobile communication technology has greatly promoted the development and progress of society, especially the 5G new generation mobile communication system, which has opened the door to the Internet of Everything and promoted the development of technologies such as the Internet of Things, big data, blockchain, autonomous driving and The vigorous development of artificial intelligence and other technical fields is bound to have a subversive impact on the future society. While 5G brings a beautiful vision to everyone, it also puts forward higher requirements for the existing base station antenna technology and performance. The frequency of 5G communication has been greatly increased, and the coverage of a single antenna of a base station has been greatly redu...

AI Technical Summary

Problems solved by technology

The frequency of 5G communication has been greatly increased, and the coverage of the single antenna of the base station has been greatly reduced, resulting in a large increase in the number of base stations. The resulting cost consumption will be the biggest obstacle in the process of 5G popularization

However, this type of antenna also has the obvious disadvantages of high profile and large volume

In the published literature, the section height of the antenna can be reduced by folding the vertical patch and slotting in the floor, but there is still a certain gap between the actual application requirements.
