Abstract
A communication antenna and radiation unit thereof with tapered clearance slots for transceiving radiation signals disposed at four corners of the radiation unit. The slots form groups and are arranged and fed by two feeding units. A middle portion of the radiation unit is a flat central platform. Peripheries of the radiation unit are turned up to form folded edges. The communication antenna includes a reflecting plate and a radiation unit operating at a low frequency. The central platform has a high-frequency radiation element. The radiation unit has a small aperture and is lightweight, so the antenna size is reduced, and a radiation performance indicator can be ensured. The radiation unit is applied to a multi-frequency antenna, has little effect on a high-frequency oscillator, and is especially suitable for a multi-frequency base station antenna with a low-frequency unit and a high-frequency unit forming an array in a nested manner.
