Abstract:
Technologies directed to a directional calibration antenna for calibration of an array antenna of a communication system are described. The communication system includes the array antenna which includes a number of antenna elements. The number of antenna elements are located in an area on a first side of a support structure. A directional antenna is located at a first height above a plane of the array antenna and at a periphery of the area. The directional antenna is pointed towards the array antenna and is located within a near field of the array antenna.
