The demand for wireless communications has been growing faster than ever, as RF/microwave technology has undoubtedly become a part of our daily lives. In wireless communications, the antenna is very important because it directly affects the signal transmission and reception. Recently, the dielectric resonator antenna (DRA) has been studied extensively due to the inherent merits of its low loss, small size, low cost, and ease of excitation. Today, the dualband antenna plays a very important role in wireless communications (e.g, 2.4/5.2GHz WLAN systems). This project is to obtain brand-new engineering formulas that determine the dimensions of the cylindrical dualband DRA. Using the result, the wideband cylindrical DRA will also be designed by merging together the two bands of the dualband DRA. Ansoft HFSS will be used to simulate the dualband and wideband antennas and the results will be verified by measurements.
