Abstract : The Dielectric Resonator Antenna (DRA) is one of the efficient radiator which is used to achieve broadband and cost effective communication in wireless technology. The Substrate Integrated Waveguide (SIW) technology is the most assuring structure for implementation of circuits and components for millimeter wave and microwave applications. A design approach to improve the impedance bandwidth of cavity backed dumbbell slot antenna using Substrate Integrated Waveguide for X band (8-12 GHz) application is presented in this paper. The proposed design improves impedance bandwidth by the use of Cylindrical Dielectric Resonator Antenna and metal strip along with offset feeding technique. The performance characteristics of the proposed antenna design is evaluated and studied.
