5G millimeter wave filtering wideband antenna

Abstract

The invention discloses a 5G millimeter wave filtering wideband antenna, comprising a top-down six-layer structure as follows: a pair of metal patches and a first metal strip; a pair of second metal strips; a pair of third metal strips; an open-circuit metal strip; a metal earth with a pair of groove lines and a through hole; a microstrip line, wherein a pair of metal patches constitute an electric dipole; a first metallized via, a third metallized via, and a second metal strip constitute a sidewall of the magnetic dipole; the first metal strip, the third metal strip, the second metallized via, the fourth metallized via, and the microstrip line constitute a feeding structure. The invention takes into account the antenna bandwidth, filtering characteristics and low-profile AiP structure, the bandwidth covers a plurality of 5G millimeter wave frequency bands, the filtering is realized through the upper and lower sideband radiation zeros, and the magnetic dipole and the feeder are mixed and connected with the metal strip through the metallized vias to achieve the low-profile design effect.

Description

technical field [0001] The invention relates to the field of microwave communication, in particular to a 5G millimeter wave filter broadband antenna. Background technique [0002] Compared with the fourth-generation mobile communication technology, the fifth-generation mobile communication (5G) technology will be greatly improved in terms of rate, delay, number of connections, and mobility, and 5G millimeter wave has better rate performance. In China, the 5G millimeter wave operating frequency bands are 24.75-27.5GHz and 37-42.5GHz. If a broadband antenna (bandwidth greater than 53%) can cover these two frequency bands at the same time, it will reduce the number of antennas and receiving and sending components, which is conducive to 5G mobile Terminal miniaturization. The broadband millimeter-wave antenna with filtering characteristics can effectively reduce the impact of out-of-band signals on the system, and to a certain extent reduce the system's demand for filters. At ...
