This project proposes a design and development technique for bandwidth enhancement of cylindrical dielectric resonator (DRA) energized with an L Aperture feed is presented, which is suitable for wideband application. It is implemented by modifying the dimensions of Cylindrical Dielectric Resonator Antenna (CDRA). It reduces the effective permittivity because effective permittivity is inversely proportional to resonant frequency, so that it increases the resonant frequency of Dielectric Resonator Antenna (DRA). The substrate and Dielectric material used for investigation is Rogers RT 5880 and Alumina Ceramic of dielectric constant 9.9. Parametric analysis on the antenna is performed using Ansoft HFSS solver by varying different parameter and shape of Dielectric Resonator and length of feed line. The objective of this project is to optimize antenna parameters and thereby study the effects of antenna dimensions Length (L), Width (W) and substrate parameters, relative dielectric constant, substrate thickness on its performance. The novel exciting technique achieves a 2:1 VSWR bandwidth of 11.76% and peak and average gain of the proposed antenna is 8.92dBi. This project introduces to design antenna operating at 4.42GHz based on the Cylindrical Dielectric Resonator Antenna (CDRA) radius of 10 mm and height of 10mm. The variation of bandwidth for different feed parameters is also studied. High Frequency Structure Simulator (HFSS) software will be used to design a Cylindrical Dielectric Resonator Antenna.
