Abstract

A central symmetric horizontally-polarized broadband omnibearing array antenna comprises a round dielectric plate, wherein a power division feed network is arranged on a surface of the round dielectric plate, a common disc metal ground is arranged on the other surface of the round dielectric plate and outwards extends to form a circular metal foil, the circular metal foil is uniformly partitioned into four circular arc printing dipoles by a first radial gap, a second radial gap, a third radial gap and a fourth radial gap which are arranged on the circular metal foil, a radial intermediate gap is formed on each circular arc printing dipole and arranged on a radial symmetric central line of the circular arc printing dipole, a radial rectangular coupling branch is arranged in each radial gap, arc gaps are connected to the inner side ends of the radial gaps, all arc gaps are concylic by taking the center of the common disc metal ground as a circle center, an arc guide branch is arranged on the outer side of each radial gap, and all arc guide branches are arranged on a circumference taking the center of the common disc metal ground as the circle center.

Description

technical field [0001] The invention relates to a center-symmetrical horizontally polarized broadband omnidirectional antenna array and an adjustment method thereof, belonging to antennas for mobile communication base stations and other facility equipment. Background technique [0002] With the development of mobile communication technology, base station antennas and local transit base station antennas are required not only to be vertically polarized, but also to be horizontally polarized, not only for high frequency bands (1710MHz-2700MHz) to be horizontally and vertically polarized, but also for low frequency bands (698MHz-960MHz) is horizontal and vertical dual polarization. In order to smoothly realize the integrated design of horizontal polarization and vertical polarization, it is required that the low-frequency horizontally polarized antenna has good out-of-roundness and has a perforation in the center. Existing horizontally polarized antenna technologies cannot meet ...
