The objective of this thesis was to analyze a Coplanar Waveguide (CPW)-fed folded slot antenna using the Finite Difference Time Domain (FDTD) method. Important parameters such as S-parameters and the input impedance of the antenna were simulated using XFDTD software and were analyzed. An important goal of this thesis was to provide design information about the folded slot antenna. For this purpose the effects of antenna layout on the resonant frequency and the bandwidth of the antenna were investigated. First the effect of adding more number of slots to the basic CPW-fed folded slot antenna geometry on the S-parameters, the input impedance and the radiation patterns of the antenna were studied. Next the width of the slot was varied and the effect of changing this design parameter of the antenna was analyzed. Finally the slot separation was varied and its effect on the antenna parameters is studied. This work concluded that, by including additional slots, the input impedance of the antenna can be controlled over a wide range.
