Abstract

A wideband patch loaded dielectric resonator antenna (DRA) is discussed here. The rectangular ring shaped slot coupling is used to excite the proposed antenna. In this paper, rectangular ring shaped slot coupled DRA and patch loaded DRA is studied and compared. The combined effect of patch radiator with rectangular ring shaped slot coupled DRA, on the return loss is observed. Simulation is done using Ansoft HFSS which is based on finite element method. Simple DRA resonates at two frequencies centered at 2. 25 GHz having return loss of -14. 41 db and 4. 61GHz with a return loss of -19. 29db; The patch loaded DRA shows resonance at frequencies centered around 2. 19GHz having return loss of -32. 3db and 4. 4GHz with a return loss of -29. 18db. The patch loaded DRA is based on the multi resonance technique that combines the resonance of slot coupled dielectric resonator and micro strip patch antenna. The bandwidth achieved for simple DRA is 26. 8 % while patch loaded DRA offers 44. 1 %. As the patch loaded DRA has larger bandwidth, may be used for wideband WLAN applications like WiFi, Bluetooth, Wimax etc.
