Problems solved by technology

The antenna has the advantages of simple structure and easy processing, but because of the large cross-polarization caused by the feeding probe and the small beam width, the unit antenna cannot be well applied to millimeter-wave phased array antennas
[0003] There may not be a millimeter wave magnetoelectric dipole antenna with differential feed, dual polarization and wide beam at the same time, so it is necessary to design a differential feed dual polarization wide beam magnetoelectric dipole antenna

Abstract

The invention discloses a millimeter wave differential feed dual-polarization wide-beam magnetoelectric dipole antenna. The antenna comprises four square metal patches, a differential coaxial feed structure, four groups of metal via holes, a dielectric substrate, a metal floor and a vertical metal fence, and the differential coaxial feed structure comprises a cross-shaped metal patch and four feed coaxial lines located under the metal floor. According to the invention, a differential dual-polarization coaxial feed form is adopted, the antenna has the characteristics of low cross polarization and good polarization diversity capability, has the characteristic of wide beam by adding the vertical metal column fence around the magnetoelectric dipole antenna, and can be applied to a linear phased array, and the bandwidth can cover a 5G millimeter wave frequency band.

Description

technical field [0001] The invention relates to the technical field of wireless mobile communication, in particular to a millimeter-wave differential feeding dual-polarized wide-beam magnetoelectric dipole antenna. Background technique [0002] With the development of wireless communication technology, the performance requirements of the antenna are getting higher and higher. In modern wireless systems, dual-polarized antennas have become a hot topic in current research, because of their good polarization diversity capabilities, they can increase channel capacity and improve spectral efficiency. Compared with the traditional mechanical scanning antenna, the phased array antenna has the characteristics of fast scanning speed, small size and good stability; since the total pattern of the array antenna is the product of the pattern of the active unit and the array factor, in order to make The array can have a relatively small gain flatness during the scanning process. A common...
