Design Of Patch Antennas Using Different Optimization Techniques For Microwave Applications

Abstract

A significant development in the wireless communication system necessitates low cost, newlinesmall size, and lightweight antenna structures. Microstrip patch antennas (MPAs) are newlinethe appropriate candidates for satisfying all these above requirements. Therefore, newlinevarious MPAs are optimally designed for several microwave frequency applications. newlineSpecifically, fifteen different MPAs are designed which operate at different microwave newlinefrequencies within the range of 2 GHz to 12 GHz. newlineMy research work of fifteen different MPA designs is organized into nine newlinedissertation chapters. The Introduction is the first chapter and Concluding Remarks is newlinethe last chapter. The literatures referred for my research are presented in Chapter-2. In newlineChapter-3 various optimization algorithms that are used for my MPA designs are briefly newlinediscussed. In the rest five chapters, fifteen MPAs designed for microwave frequency newlineapplications are explained. First of all, three simple patch designs are considered for the newlineoptimal design for some specific applications. The first design is a simple rectangular newlinepatch antenna (RPA) resonating at 5 GHz frequency. The dimensions of this RPA are newlineoptimized using the Bat Search Optimization Algorithm. newline
