Discussion on Teaching Cases of Virtual Simulation Experiment for Circular Polarized Antennas Based on HFSS
In order to improve teaching effectiveness and let the students to solve the problem of being unable to understand the abstract concept of circular polarization in electromagnetic fields and waves courses,we use a high frequency structure simulator(HFSS)to construct a virtual simulation experiment teaching case for designing circular polarization antenna to simulate the generation of circular polarization wave.Through circular polarization antenna simulation teaching case,the students can intuitively understand circular polarization wave.In the simulation teaching,we use graphics and data to discuss the generation procedure of the circular polarization wave,and the students can understand the circular polarization antenna and analyze the characteristics of circular polarization wave,and then deeply understand the generation of circular polarization wave and design of circular polarization antenna.The vivid circular polarization wave teaching case not only helps the student understand the abstract concept of circular polarization,but also stimulates their strong interest in learning electromagnetic fields and waves.
