Achievement of a bifurcated beam by a bend array configuration

Abstract

For the next generation (5G) mobile base station antennas, authors are developing a cylindrical lens antenna featuring a simple configuration compared to the present array antenna configuration. In order to achieve a cylindrical lens antenna, feed element should produce a bifurcated beam radiation. In this paper, the bifurcated beam is conformed by a bend array configuration. Relations of array element number and objective beam shape are investigated.
