Wideband Dual-Polarized Dielectric Rod Antenna Array with Near-Constant Beam Width

A novel modification of linear antenna array of dielectric rod antennas for operation over the mobile communication frequency band 3.2-6.3 GHz with the dual polarizations tilted by angle ±45° to horizon is proposed and studied. Antenna array provides the near-constant beam width of radiation pattern in the horizontal plane within frequency band about the octave. Proposed concept shows potential for implementation of dual polarized wideband antenna arrays with high characteristics.
