The Development Of Dual Band Cylindrical Dielectric Resonator Antenna

Antenna with ability to operate in dual band frequency is among famous research and manufacturing product. It can work efficiently and compatible with current technologies devices. Throughout this paper, a design of cylindrical dielectric resonator antenna (DRA) is produce by manipulating the aperture coupling technique. The aperture coupling technique used is C-shaped slot and the parameter that varies is the position and dimension of the C-shaped slot. The constant parameters in this project is the size and the length of the microstrip feeder line which act as the transmission line for the signals and also the size of cylindrical DRA which function to radiate the signals. The results will be analyzed based on the resonant frequency impedance bandwidth, return loss, and radiation pattern. The desired antenna design must achieve the objective, which is to operate at dual band frequency 3.6 GHz and 5.2 GHz. The effect of tuning the slot positions and dimensions on the resonant frequency are also investigate and discussed.
