Abstract: This application provides an antenna and a communication device, and relates to the field of communication technologies, to resolve a problem that the antenna cannot effectively balance a narrow beam width and a small height of a cross section. In the antenna provided in this application, the beam width of the first radiating element can be effectively narrowed by configuring the first conductive part, and the height of the cross section of the antenna is not significantly increased.

Abstract: This disclosure provides an antenna and a base station device. The antenna includes: a plurality of first frequency band antenna groups; a plurality of second frequency band radiating elements; and a reflection plate on which a reflection plate through hole is provided. Each first frequency band radiating element includes: a first balun structure and a first signal transmission structure, which pass through the reflection plate through hole. A phase shifter includes a first phase shifter cavity, a choke cavity, and a first feed network signal transmission structure located in the first phase shifter cavity. A part that is of the first balun structure and that is located on a second side of the reflection plate is located in the choke cavity.

Abstract: Embodiment high-frequency radiator includes two plus and minus 45-degree single-polarized radiators. The single-polarized radiator includes a radiation arm, a balun, a feeder circuit, a filter, and a ground plane. The radiation arm and the balun are electrically connected. The feeder circuit and the balun are separately disposed on two surfaces of a first dielectric plate that is placed vertically. The ground plane is disposed on a downward surface of a second dielectric plate that is placed horizontally. The first dielectric plate is vertically disposed on the second dielectric plate, and the filter includes a capacitor branch and an inductor branch. The inductor branch is disposed on a same surface of the first dielectric plate as the balun, the inductor branch is separately electrically connected to the balun and the ground plane, and the capacitor branch is coupled to the ground plane.
