Investigation on Mutual Coupling of Aperture Coupled Cylindrical Dielectric Resonator Antenna (DRA)

Journal of Engineering and Science Research, 2018
In this research, study on mutual coupling of aperture coupled cylindrical DRA and its influence on return loss, radiation pattern including the directivity, gain and bandwidth was computed and illustrated. The DRA was excited by a micro strip line with aperture coupled slots where the slot locations were calculated using the characteristic of standing
