BASE STATION, AND BROADBAND DUAL-POLARIZED FILTERING MAGNETO-ELECTRIC DIPOLE ANTENNA AND RADIATION UNIT THEREOF

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 comprises two groups of dipoles with mutually orthogonal polarization directions, wherein each group of dipoles comprises two radiators arranged opposite each other. A balun structure comprises four groups of balun assemblies. Each group of balun assemblies comprises two balun grounds arranged opposite each other at an interval, and a feeder line and an open stub arranged opposite each other at an interval and electrically connected to each other, wherein one balun ground is electrically connected to one radiator, and the other balun ground is electrically connected to the other adjacent radiator; the feeder line and one balun ground are arranged opposite each other at an interval; the open stub and the other balun ground are arranged opposite each other at an interval; and the balun grounds are arranged between the feeder line and the open stub. Mutual coupling between radiation units is avoided, and therefore, the broadband dual-polarized filtering magneto-electric dipole antenna using the radiation unit has a good performance; moreover, the base station using the broadband dual-polarized filtering magneto-electric dipole antenna also has a good overall performance.
