Abstract
This thesis focuses on the analysis and design of microstrip antennas working in a
wide range of frequency bands (WiMAX, UWB, Ku-band, mm-Wave), and based
on electromagnetic band gap (EBG) structures. A mushroom-like EBG structurebased
substrate is designed, analyzed and optimized using a technique based on
the combination of an evolutionary heuristic optimization algorithm (genetic algorithm)
with the Computer Simulation Technology (CST) Microwave Studio, for
WiMAX applications. Next, a topology optimized ultra wideband antenna alongside
a compact FSS layer, covering the UWB spectrum of frequencies, are designed
and analyzed. The simulation results and measurements obtained are compared
with various works in the open literature. Finally, Fabry-Pérot resonator antennas
based on the proposed PRS structures, generated and optimized using an automatic
synthesis system, based on a VBA link between MATLAB and CST Microwave
studio, were designed, analyzed and fabricated. The obtained results are compared
with other research in the open literature, where it is clearly indicated that the
proposed designs could be potential candidates for high gain and wideband systems
in Ku-band and mm-wave applications, such as the 5G.
