Design of Shaped Offset Dual-Reflector Antenna for 5G Mobile Base Station

In 5G mobile communication system, new technical subjects such as millimeter wave, small cell size and multibeams at a base station will be introduced in relating to radio wave technologies. For a millimeter wave base station antenna, an aperture antenna such as a reflector will be possible. In this paper, reflector shaping method of offset dual-reflector is shown. Based on the shaping method, a reflector shaping program is developed on a MATLAB software. Some base station antennas are designed and installation conditions on a base station are examined.
