US 10,483,635 B2 · Multi-frequency communications antenna and base station

Abstract

Embodiments of the present invention provide a multi-frequency communications antenna and a base station. The multi-frequency communications antenna includes at least one low-frequency array, at least one high-frequency array, at least one circuit board disposed corresponding to the high-frequency array, and a reflection panel, where a filtering component configured to decouple filtering is disposed on the circuit board, a first end of the filtering component is electrically connected to the high-frequency array, and a second end of the filtering component is electrically connected to a signal ground layer of the circuit board. The filtering component configured to decouple filtering that is shown in this embodiment is disposed on the circuit board, which causes a small damage to an array radiation environment.
