Abstract :
CPW-fed dual rectangular ceramic dielectric resonator antennas through inductively coupled slots have been studied by experiment. A better bandwidth is achieved if these compare with only single dielectric resonator as antennas. Also, these antennas can be easily do the input impedance matching using several parameters like adjusting the length of inductive slots, the space between dielectric resonators, and the offset distance of DR center to the center of end inductive slots.
