Abstract

The invention discloses a 5G millimeter wave dual-band dual-array antenna, and the antenna comprises low- frequency and high-frequency antenna units arranged at intervals in sequence, wherein the low-frequency and high-frequency antenna units respectively comprise antenna model units in different sizes. Each antenna model unit comprises a five-layer structure, wherein the first layer is a metal patch of a loading slot, the second and third layers constitute a folded open circuit resonator for loading a short-circuit branch. The resonant and the metal patches of the loading slot are used for generating two reflection zero points so as to increase the bandwidth of the antenna. Through the even mode of the resonator, the resonator and the patches are coupled to generate controllable low-end and high-end radiation zero points, thereby improving the near-field and far-field isolation between the dual-array antennas to form two arrays which work at different frequencies and have two reflection zero points and two radiation zero points. Moreover, the two arrays are small in overall size and are isolated from each other. The coupling between the patches and the resonator is controlled by changing the size of the groove, thereby achieving a low profile design of the antenna.

Description

technical field

[0001] The invention relates to the field of microwave communication, in particular to a 5G millimeter-wave dual-band dual-array antenna. Background technique

[0002] The fifth-generation mobile communication technology (5G) proposes millimeter-wave application requirements (Chinese frequency bands are 24.75-27.5GHz and 37-42.5GHz), aiming to achieve high-speed data transmission through broadband spectrum. In order to cover these two millimeter-wave frequency bands, there can be single-antenna dual-band antennas, dual-antenna dual-band antennas, and broadband antennas. However, the broadband antenna solution requires a bandwidth of 53%, which is difficult to design and has a complex structure. Because the single-antenna dual-band solution can be optimized separately for the two frequency bands, the design difficulty is reduced, and the structure is relatively simple. Therefore, dual-band dual millimeter-wave antennas are an important technology for 5G milli...
