Özet:This thesis includes the design, simulation, production and measurement of a differential fed magneto-electric dipole antenna with cavity operating at ultrawideband (3.3 GHz – 10 GHz). This antenna consists of a differential feeding structure, an electric dipole, a magnetic dipole and a cavity. The ultra-wideband operation is achieved through the use of differential feeding structure and cavity. A step-by-step procedure is followed during the design process of the differential fed magneto-electric dipole antenna with cavity. First, a gamma-shaped strip fed magneto-electric dipole antenna is designed to study the effects of the antenna parameters on the return loss and the characteristics of the antenna gain. These parametric analyses are done in Ansys HFSS, a high frequency electromagnetic field simulation program. By the help of the experience gained through these parametric analyses, a differential fed magneto-electric dipole antenna is designed and simulated. Then, in order to achieve design requirements a cavity is incorporated into the design. vi Finally, the designed differential fed magneto-electric dipole antenna with cavity is manufactured, measured, and its performance is compared with simulation results.
