Abstract
A high gain dual-band printed antenna is proposed for LTE base stations applications. The established 60â¯Ãâ¯60â¯mm2 broadband antenna structure is composed of two perpendicular U-shaped and L-shaped monopole antennas which are located vertically on ground plane printed on 1.6â¯mm thick FR4 substrate. A metallized wall is connected to the substrate which forms a corner reflector. A coaxial cable at the common center of the monopoles is adopted to excite the antenna. Wise implementation of the conductive elements and finely tuning of the monopoles dimensions yield the excitation of two resonances and dual band operation achievement. The presented antenna achieves bandwidths of 1.61-1.86â¯GHz and 2.25-2.45â¯GHz suitable for LTE applications. Stable radiation pattern, small size, cost effective fabrication, and high peak gain values of 10â¯dBi and 9.5â¯dBi at two operating bands are the prominent features of the proposed antenna topology.
