摘要： Disclosed are a base station, and a broadband dual-polarized filtering magneto-electric dipole antenna and a radiation unit thereof. A radiation structure includes two dipoles with a polarization direction orthogonal to each other. Each dipole includes two radiators arranged opposite to each other. A balun structure includes four balun assemblies, each balun assembly includes two balun grounds arranged opposite to each other at an interval, and a feeder line and an open-stub arranged opposite to each other at an interval and electrically connected to each other. One balun ground is electrically connected to one radiator, the other balun ground is electrically connected to the other adjacent radiator. The feeder line and one balun ground are arranged opposite to each other at an interval. The open-stub and the other balun ground are arranged opposite to each other at an interval. The balun grounds are arranged between the feeder line and the open-stub.
