Problems solved by technology

[0002] The existing electric dipole Yagi antenna array realizes the polarization characteristic parallel to the plane where the antenna is located. If vertical polarization is to be provided, the antenna needs to be perpendicular to the floor, which occupies a large antenna height, which seriously affects the aesthetics and concealment of the antenna.

Abstract

The invention discloses a magnetic dipole yagi antenna. The magnetic dipole yagi antenna comprises four side-by-side and parallel metal patch radiating units which are printed on a dielectric plate, wherein the metal patch radiating units are a reflection coupling unit, an excitation unit, a first lead coupling unit and a second lead coupling unit in order. Adjacent metal patch radiating units are spaced. The excitation unit comprises upper and lower rectangular metal patches and a short circuit pin group. Upper and lower rectangular metal patches are respectively located on upper and lower surfaces of the dielectric plate. Upper and lower rectangular metal patches are communicated through the short circuit pin group. The reflection coupling unit, the first lead coupling unit and the second lead coupling unit respectively comprise first and second rectangular metal patches and a third short circuit pin group. First and second rectangular metal patches are respectively located on upper and lower surfaces of the dielectric plate. First and second rectangular metal patches are communicated through the third short circuit pin group. According to the invention, the magnetic dipole radiating units are used to construct a yagi antenna array, and the magnetic dipole yagi antenna has the characteristics of low profile, wide frequency band and good directivity.

Description

technical field [0001] The present invention relates to the field of antenna design, more specifically, to a magnetic dipole Yagi antenna. Background technique [0002] The existing electric dipole Yagi antenna array realizes the polarization characteristic parallel to the plane where the antenna is located. If vertical polarization is to be provided, the antenna needs to be perpendicular to the floor, which occupies a large antenna height, which seriously affects the aesthetics and concealment of the antenna. . Contents of the invention [0003] In order to overcome at least one defect (deficiency) of the above-mentioned prior art, the present invention provides a magnetic dipole Yagi antenna. This antenna uses a magnetic dipole radiation unit to construct a Yagi antenna, which has the characteristics of low profile, wide frequency band and good directivity. [0004] In order to solve the problems of the technologies described above, the technical solution of the presen...
