Abstract: 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.

Abstract: A millimeter wave filtering antenna and a wireless communication device are disclosed. The millimeter wave filtering antenna includes a parasitic unit, a feeding unit and a feeding network. The parasitic unit includes at least one quadrilateral parasitic patch and at least one cross shaped parasitic patch, both of which are nested and combined with each other. The feeding unit includes a feeding patch, and the feeding patch is loaded with a short-circuit patch to form coupling. The feeding network feeds the feeding unit. The wireless communication device includes a millimeter wave filtering antenna according to the present disclosure. The radiation performance of the antenna can not only realize the filtering characteristics with high roll-off and high isolation, but also ensure that no additional insertion loss is introduced.

Abstract: The invention discloses a dual-polarized filtering magneto-electric dipole antenna, which comprises an upper dielectric substrate and a lower dielectric substrate. The upper surface of the upper dielectric substrate is printed with a radiator structure, and the lower dielectric substrate is printed with a slot coupling feed network; the radiator structure comprises four parasitic patches loaded with symmetrical slots. The parasitic patches are loaded with short-circuit probes, and the slot coupling feed network comprises two orthogonal sets of Y-shaped feeders and cross-shaped slots, and the cross-shaped slots are printed on a metal floor. The new parasitic slot structures on the radiator structure increases the bandwidth while introducing a high roll-off band edge filtering effect, and combined with the slot coupling feed network with filtering function to achieve good band-pass filtering characteristics and hardly introduce additional insertion loss.
