As technology advances in different areas for various requirements of the antenna higher and higher, so the analysis of microstrip antenna size and performance plays an important role. Article uses HFSS microstrip antenna design, the paper introduces and analyzes the basic concepts and performance parameters of the antenna, with emphasis on the microstrip antenna. This article describes the analysis of the microstrip antenna and antenna simulation in HFSS simulation and analysis functions, simple microstrip antenna.
