| dc.description.abstract | The thesis covers two aspects of microstrip antenna designs. The first is the analysis and design of single element narrowband rectangular microstrip antenna which operates at the central frequency of 2.4 GHz and the second aspect is the design of five element broadband Log Periodic microstrip antenna. Both antennas have been modeled, designed and simulated. Basically, transmission line and cavity modeling are going to use to model both antennas. First, the design parameters for single element of rectangular patch antenna have been calculated from the transmission line model equation and extend the antenna design to five element log periodic microstrip antenna using log periodic analytical technique. The simulation process has been done through momentum simulation using Empire software. Each data from the Finite Difference Time Domain Method (FDTD) simulation extract and combine with the microstrip transmission line. The rectangular microstrip antenna design uses Flame Retardant 4, FR4, microstrip board with dielectric constant 4.7, scaling factor 0.95 and loss tangent is 0.019. The properties of antenna such as bandwidth, S parameter has been investigated and compared between a single element rectangular and a five element log periodic rectangular microstrip antenna. . | en_US |
