| 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. |
