Abstract

In this paper cylindrical Dielectric Resonator is simultaneously used as a Filter and an Antenna named as Dielectric Resonator Antenna Filter (DRAF), at X band. We can tune and design Filter part and Antenna part of DRAF almost independently, operating frequencies of antenna and filter can be made same or different. The independent control of Antenna part and Filter part in DRAF comes from the orthogonal nature of two modes TE_01δ for DRF and HEM_11δ for DRA of the Dielectric Resonator. Antenna part has been excited by two different feeding methods. For coaxial feed method operating frequencies are 10.86 GHz (DRF) and 8.64 GHz (DRA) and for microstrip feed method operating frequencies are 11.18 GHz (DRF) and 8.12 GHz (DRA).
