Abstract

The present disclosure relates to an antenna for a wireless communication system. The antenna comprises a reflector having a front side for transmitting a signal and a back side opposite to the front side; an antenna oscillator disposed on the front side of the reflector; a phase shifter network disposed on the back side of the reflector; and an antenna oscillator fixing apparatus disposed on the front side of the reflector and configured to fix the antenna oscillator to the front side of the reflector. In addition, the present disclosure also relates to a method for fixing an antenna oscillator to a reflector. With the antenna and the fixing method according to the present disclosure, it is possible to manufacture an antenna with an antenna oscillator that is easy to dismantle without damaging an existing phase shifter network, which will improve maintainability of the antenna according to the present disclosure dramatically and also reduce the cost of maintenance and repairs.
