The embodiment of the invention discloses a millimeter wave dual-polarization end-fire beam scanning antenna and an antenna array, and the antenna comprises a first dielectric plate, a grounding platedisposed at the bottom of the first dielectric plate, and a magnetic dipole antenna and a printed electric dipole antenna are disposed on the grounding plate in parallel. The magnetic dipole antennacomprises a magnetic radiator, the magnetic radiator comprises a top plate and a side wall connected with the grounding plate and the top plate of the magnetic radiator, the side wall of the magneticradiator is provided with a first opening, and the printed electric dipole antenna is arranged close to the first opening; and the radiation directions of the printed electric dipole antenna and the magnetic dipole antenna are the same, and the polarization directions of the printed electric dipole antenna and the magnetic dipole antenna are mutually orthogonal. Therefore, compared with a dual-polarized antenna formed by combining vertically-placed and horizontally-placed end-fire antennas in the prior art, the dual-polarized antenna has the advantages that the profile height is smaller,integration is easier, and the processing difficulty is reduced.
Description
technical field [0001] The embodiments of the present application relate to the field of antenna technologies, and in particular, to a millimeter-wave dual-polarized end-fire beam scanning antenna and an antenna array. Background technique [0002] With the rapid progress of mobile communication technology and the rapid popularization of intelligent terminals, the business demands of mobile users and wireless data are showing explosive growth. In order to meet the communication requirements, the fifth-generation mobile communication system (5G) is expected to work in the millimeter wave band, which will bring new challenges to the application of antennas to mobile terminals. Millimeter wave technology is one of the key technologies for 5G mobile communications. [0003] Millimeter wave communication belongs to microwave communication. The wavelength range of millimeter wave is 0.1~10mm, and the frequency range is 30~3000GHz. It has the characteristics of small beam, high an...
