Simulation Analysis And Optimization Of Microstrip Patch Antennas

Microstrip patch antenna has been widely used because of its own advantages, such as: low profile, light weight, easy fabrication, conformability to mounting hosts. But, with the increased demands of antenna quality for different purposes, how to analyze the physical sizes and performance parameters of microstrip antenna will be more and more important. So, this thesis used Ansoft HFSS software to optimization and do research about performance changes of microstrip antenna in several physical sizes.The thesis introduced basic concepts and parameters of antenna, focus on microstrip antenna, then the classical microstrip antenna and its methods are illustrated. Be familiar with simulation function and simulation process of Ansoft HFSS software, did simulation analysis about microstrip antenna in two design methods. Finally, simulated the microstrip patch antenna which includes cutting corner, acquired the optimization program of antenna performance.The thesis provided effective approach of engineering optimized design of microstrip antenna, confirmed that functional simulation of Ansoft HFSS software can do optimization design in more complex antenna projects, compared to more programs, it will ensure the precision and reduce the design cost.
