Abstract
The present invention discloses a dual-polarized wide-stopband filtering antenna and a communications device, the antenna comprising a dielectric substrate, a metal ground plate, a metal radiating patch, metal feeding arms, a metal square ring stub, metal transverse stubs, and metal probes, wherein the dielectric substrate is a rectangular cavity structure, the metal ground plate is disposed on the bottom surface of the dielectric substrate, and the metal radiating patch is disposed in the middle of the top surface of the dielectric substrate; the metal transverse stubs and the metal square ring stub are located inside the rectangular cavity and are connected on the same layer; the metal feeding arms are located between the metal square ring stub and the metal radiating patch; one end of the metal probe and a circular hole disposed on the metal ground plate form a coaxial feeding structure, and the other end of the metal probe is linked with the midpoint of the metal transverse stub and it is simultaneously connected to one end of the metal feeding arm to form a dual-polarized differential feeding structure; and the metal probes are connected to the metal transverse stubs. The antenna has a simple structure, can greatly reduce the volume of a radio frequency front end, and has no additional insertion loss.
