Abstract

The objective of this thesis was to analyze a Coaxial-Fed U-slot Rectangular Patch Antenna using Finite Difference Time Domain (FDTD) method. Important parameters such as S-parameters and 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 U-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 varying slot width on the S-parameters, Voltage Standing Wave Ratio (VSWR) and Input Impedance were studied. Next the length of the slot was varied and effect of changing this design parameter of the antenna was analyzed. Finally the substrate thickness was varied and its effect on the antenna parameters is studied. This work concluded that by varying antenna dimensions such as slot width, slot length and substrate thickness, higher bandwidth could be achieved with required impedance matching.
