Abstract—An initial cuboid shape dielectric resonator antenna is made from a ceramic compound with a high dielectric constant of 30. A feeding mechanism that consists of a coaxial probe in the middle of the antenna is installed underneath, Parasitic feed elements are used to guide the flow of the surface current into the desired direction. Each parasitic feed possesses a switch to control the surface current flow and obtain a reconfigurable pattern. The impedance bandwidth of the proposed antenna is 320 MHz from 2.45–2.72 GHz with a total efficiency exceeding 96%, which is suitable for long-term evolution (LTE) of bands 7 (2,500–2,570 MHz, 2,620–2,690 MHz) and 38 (2.57–2.62 GHz) femtocell base stations. The proposed antenna is fabricated, and results indicate satisfactory agreement between simulated and fabricated antennas.
