چکیده انگلیسی
This article presents a design of multiband Rectangular Dielectric Resonator Antenna (RDRA) using two elements with different aspect ratio. The proposed DRA is excited by means of micro-strip feedline with double stubs which not only improves the bandwidth of each band but also achieves good impedance matching. The proposed DRA operates at “C” band, “WLAN” and “X” band frequencies and yields wide bandwidth of about 6.5%, 13.5% and 17.4% respectively. Two Rectangular DRs of completely different aspect ratio and double stub microstrip feeding achieve this multiband operation. The designed antenna is very compact and has a volume of 1737Â mm3 only. It provides stable radiation patterns in all the three bands and has a maximum gain of 6.35Â dBi with radiation efficiency of more than 82% over the operating band of frequencies. The proposed antenna has been studied, analyzed and optimized using Ansoft HFSS simulation software. The designed antenna is fabricated, tested and compared with other multiband designs. Good agreement is achieved between simulated and measured ones.
