Abstract
(EN)
Provided in the present application are a high-frequency radiator, a multi-frequency array antenna, and a base station. The high-frequency radiator of the present application comprises two plus and minus 45-degree single-polarized radiators; each single-polarized radiator comprises a radiation arm, a balun, a feed circuit, a filter, and a ground layer; the radiation arm is electrically connected to the balun; the feed circuit and the balun are respectively disposed on two surfaces of a first dielectric plate which is placed vertically; the ground layer is disposed on the downward surface of a second dielectric plate which is placed horizontally; the first dielectric player is disposed on the second dielectric plate in a perpendicular manner; the filter comprises a capacitor branch and an inductor branch, the inductor branch is disposed on the same surface of the first dielectric plate as the balun, the inductor branch is electrically connected to the balun and the ground layer, separately, and the capacitor branch is coupled to the ground layer; the feed circuit is used for feeding the high-frequency radiator; the filter is used for weakening the effect of the high-frequency radiator on a low-frequency radiator. The present application solves the problem of common mode resonance of the high-frequency radiator; moreover, the bandwidth of the antenna is not affected, and the processing cost is low.
