Problems solved by technology

Some high-gain broadband WiFi antennas are designed with a series feed structure, but the disadvantage of this antenna is that the maximum radiation direction of the pattern will shift as the frequency changes, which is not conducive to practical applications
Some antennas use a parallel one-to-three structure. This structure has relatively high gain and stability, but the bandwidth cannot be extended very wide.

Abstract

The invention provides an omnidirectional broadband WiFi antenna applied to 5G and 6G frequency bands. The antenna comprises: a dielectric substrate provided with a first side surface and a second side surface which are opposite to each other; a coplanar waveguide structure arranged on the first side surface of the dielectric substrate and comprising a central conductor belt and radiation patches symmetrically arranged on the two sides of the central conductor belt; load patches arranged at two ends of the central conductor belt and connected with the central conductor belt; a radiation patch connecting line arranged on the second side surface of the dielectric substrate, wherein the two ends of the radiation patch connecting line are respectively connected with the radiation patches on the two sides of the central conductor belt through metal via holes penetrating through the dielectric substrate; a feeder line arranged on the second side surface of the dielectric substrate and connected with a feeding point on the central conductor belt; and choking wires symmetrically arranged on the two sides of the feeder line and connected with the radiation patch through the metal via holes. The omnidirectional broadband WiFi antenna applied to the 5G and 6G frequency bands can cover the frequency bands of 5.15 to 5.85 GHz and 5.925 to 7.125 GHz at the same time, and has the characteristics of wide broadband, low out-of-roundness and high gain.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular, to an omnidirectional broadband WiFi antenna applied to 5G and 6G frequency bands. Background technique [0002] With the rapid development of the number of WiFi users, WiFi wireless communication systems in the 2.45GHz and 5GHz frequency bands cannot meet the ever-changing needs of today's users, and in order to reduce system space, it is very important to deploy broadband WiFi wireless communication systems compatible with the 5GHz and 6GHz frequency bands. necessary. Omni-directional antenna is a basic part of WiFi system because of its wide coverage and random location of signal receiver. Out-of-roundness is an important indicator of an omnidirectional antenna, which is used to describe whether the radiation gain of the antenna is consistent in all directions on the horizontal plane, and whether it can form a standard circular radiation pattern.
