Multi Beam Characteristics of Offset Spherical Reflector at 28 GHz
5G mobile base station requires multi beam antenna system to serve massive MIMO. This paper proposes an offset spherical reflector with fixed multi beam operation. The concentrated caustics on offset spherical reflector are acquired through focal region ray tracing analysis of slant incident rays for feed position determination. Then, the multi beam radiation characteristics are obtained by FEKO simulation at 28 GHz. High antenna efficiency more than 70% is ensured at beam scanning angle from 10 to 30 degrees.
