Dual-frequency omnidirectional high-speed rail antenna

Abstract

The invention discloses a dual-frequency omnidirectional high-speed rail antenna, comprising an antenna radiating element, a metal base plate and an antenna outer cover. The antenna radiating elementstands on the metal base plate. The outer cover is arranged outside the antenna radiating element. The dual-frequency omnidirectional high-speed rail antenna is characterized in that the antenna radiating element includes a high-frequency radiation branch, a low-frequency radiation branch, a radiating element feeding part and a radiating element grounding branch, the high-frequency radiation branch is connected with the low-frequency radiation branch, the radiating element feeding part and the radiating element grounding branch are respectively connected between the low-frequency radiation branch and the metal base plate, the low-frequency branch of the radiating element is parallel to the metal base plate, and the high-frequency radiation branch includes portions perpendicular and parallel to the metal base plate. The dual-frequency omnidirectional high-speed rail antenna in the invention has a simple structure and omnidirectional radiation characteristics.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an omnidirectional high-speed rail antenna. Background technique [0002] With the rapid development of mobile communication technology today, wireless communication has become an indispensable way of contact in people's daily life. On the other hand, due to its advantages of comfort, high speed and convenience, high-speed rail has become the preferred mode of transportation for people to travel long distances. Recently, my country's high-speed rail technology is leading the world, but there are still some problems to be solved in high-speed rail communication technology. When the high-speed rail is running at high speed, it is difficult to guarantee the reliability of the communication if the base station switching along the line is still used to realize the wireless communication. The 5G communication technology under research also regards mobile communications as ...

AI Technical Summary

Problems solved by technology

[0003] Most of the traditional high-speed rail antennas use directional antennas to exchange data with the base stations along the line. The problem is that in the direction of weak signal coverage, communication reliability is reduced, and there is a risk of increased bit error rate or dropped calls.

In high-speed operation, this risk will be further increased, which obviously cannot meet people's requirements for communication reliability
