Base station antennas for Sub-6 communication systems require omnidirectional and highly directional radiation patterns. This paper describes the analysis of M layer N elements cross dipole antenna working at 5 GHz with cylindrical conductor inside and radome outside. The availability of proposed structure is evaluated. Results will be presented and discussed. High gain around 12 dBi with vertical polarization and 11 dBi with horizontal polarization are observed under the limitation of roundness to ensure omnidirectional radiation.
