Abstract
The invention provides a dual polarized antenna or antenna array with a first and second radiation pattern having a first and second polarization, a method for adjustment of said antenna or antenna array and a wireless communication system comprising said antenna or antenna array. The antenna or antenna array comprises a main radiating antenna element or array of main radiating antenna elements arranged above a conductive frame. Then invention further provides an antenna or antenna array wherein a combination of conductive parasitic strips and chokes are arranged in association with the main radiating antenna element to achieve means for independently controlling beamwidths of the first and second radiation pattern a method for adjustment to achieve a desired beamwidth for each polarization, wherein the beamwidth adjustment for first and second radiation pattern is made independently of each other a wireless communication system including base stations equipped with a dual polarized antenna or antenna array according to the invention.
