Abstract :
A novel triple-band cylindrical dielectric resonator antenna using varying permittivity in φ-direction fed by coaxial probe is proposed in this paper. The proposed structure is constructed using three different materials having different permittivites. In order to determine the performance of various design parameters on resonance frequency and bandwidth, parametric studies have been performed. It is observed that the proposed structure resonate at three different frequencies of 4.93 GHz, 6.46 GHz and 7.41 GHz respectively.
