Aperture Antennas for 5G Mobile Base Stations

The fifth-generation (5G) mobile communication system will require the multi beam base station antennas. By taking into account a small antenna size at millimeter wave, any antenna types such as array, reflector and dielectric lens antennas become possible candidate. In this paper, aperture type antennas of reflector and lens are selected because of excellent multi beam performances. Fundamental antenna design technologies by a MATLAB software and expected radiation patterns by an electromagnetic simulator are shown.
