ABSTRACT:
An antenna assembly for emitting a signal. The antenna assembly includes at least two antennas which are separated into a first group and a second group. Both groups of antennas are mounted on a panel. A first phase adjuster is coupled to the fist antenna group. The first phase adjuster is also coupled to a second phase adjuster, which is also coupled to said second antenna group. The first phase adjuster is coupled to the second phase adjuster, such that an adjustment of the first phase adjuster causes an adjustment of the second phase adjuster. The first phase adjuster is adapted to adjust a phase angle of the signal of the first antenna group, while the second phase adjuster is adapted to adjust a phase angle of the signal of said second antenna group.
