Performance of Bandwidth Enhancement Technique on Coaxial Probe fed Dielectric Resonator Antennas

Neeraj Kumar; Ajay Kumar Thakur

This paper presents a comparative study of bandwidth enhancement techniques applied to a synthesized Compact Dielectric Resonator Patched Antenna (DRPA). Dielectric Resonator, itself has a good radiating power factor, which contributes to the advantages of proposed antenna system. Different techniques such as patching and perturbation of volumetric resonator source have been applied; which modify the radiating structure without contributing to the volume or area of the system. The performance of the antenna has been optimized to obtain good radiation efficiency and improve radiation pattern so as to enhance the directivity and the gain of the antenna. Theoretical performance of the proposed antennas are verified by full-wave simulations and experimental data obtained from a prototype. These results obtain verify the use of proposed antenna in different frequency of operation; this will make the suitability of antenna in frequency hopping technique. The obtained performance of proposed design, confirms the practicability of antenna in different indoor/outdoor wireless applications.
