Abstract :
This paper presents a CPW-fed capacitive slot-coupled rectangular triple dielectric resonator antenna. While the suitable arrangement in the distance between dielectric resonators, a tuning dual band or a 20% (530 MHz) wideband of impedance bandwidth, can be obtained. The radiation patterns are like the magnetic dipole patterns. Moreover, the antenna gain in the overall frequency band is near the uniform gain of 5 dBi, and then, an extra-wide gain bandwidth is achieved in the presented antenna.
