Abstract

Provided are a common-grounded edge rippled horizontal polarization broadband omnidirectional antenna array and an adjusting method of the common-grounded edge rippled horizontal polarization broadband omnidirectional antenna array. The antenna array comprises a circular dielectric slab, a power divider feed network, a public circular ring metal ground and an arc-shaped printed dipole array, wherein the circular dielectric slab is provided with a hole in the center, the power divider feed network is arranged on one surface of the circular dielectric slab and comprises a one-to-n eccentric equiamplitude same-phase power divider network and n feed microstrip lines, the public circular ring metal ground is arranged on the other surface of the circular dielectric slab and is concentric with the circular through hole, the arc-shaped printed dipole array is arranged on the other surface of the circular dielectric slab and composed of n arc-shaped printed dipoles which are evenly distributed in a circular ring shape, the middle of each arc-shaped printed dipole is connected with the public circular ring metal ground, and slits are formed in each arc-shaped printed dipole. According to the common-grounded edge rippled horizontal polarization broadband omnidirectional antenna array and the adjusting method for the common-grounded edge rippled horizontal polarization broadband omnidirectional antenna array, grooves are formed in the outer edge of each arc-shaped printed dipole, the outer edge of each arc-shaped printed dipole is made to be in a concave-convex rippled shape, and the out-of-roundness of radiation patterns of antennas is relieved.

Description

technical field [0001] The invention relates to a horizontally polarized broadband omnidirectional antenna array with a common ground fringe and an adjustment method thereof, belonging to antennas for facilities such as mobile communication base stations. 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 t...
