Abstract

The invention discloses a low-cost and low-profile broadband Massive MIMO antenna unit, comprising a conductor parasitic patch, a conductor coupling sheet, an antenna radiator and a conductor grounding layer which are arranged in turn and at intervals from top to bottom along a vertical straight line, wherein dielectric layers are arranged between adjacent parts. A vertical slot and a horizontal slot are symmetrically arranged at the center position of the conductor coupling sheet, and the vertical slot and the horizontal slot are orthogonal to each other and are used to expand the frequency bandwidth of the antenna. The antenna radiator is provided with a horizontal polarization feed point and a vertical polarization feed point with the feed directions orthogonal to each other. A first isolation slot is arranged at the center position between the horizontal polarization feed point and the vertical polarization feed point. Second isolation slots are arranged on the two sides of the horizontal polarization feed point and on the two sides of the vertical polarization feed point. The first isolation slot and the second isolation slots are used to improve the isolation between the horizontal polarization feed point and the vertical polarization feed point. The low-cost and low-profile broadband Massive MIMO antenna unit has the technical features of wide frequency bandwidth, high degree of isolation, high single-antenna gain, low cost and low profile.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a low-cost low-profile broadband Massive MIMO antenna unit. Background technique [0002] The research and development of base station equipment in the Sub6G frequency band of the fifth-generation communication 5G has gradually entered the mass production stage. Considering factors such as price, manufacturing precision, and performance stability are the key factors that affect whether a product can succeed and gain a foothold in the fierce market competition. [0003] Sub6G frequency band Some countries use 3.5GHz frequency band base stations, the frequency band is 3400-3800MHz, some use 3300-3800MHz, and Japan also includes 4000-4100MHz. The product development of major wireless product providers is in full swing, and the demand for Massive MIMO (Multiple-Input Multiple-Output) antennas is also a variety of different frequency requirements, which leads to the inability to sha...
