Abstract: This paper discusses the characteristics, structure, excitation method, principle, etc. of slot antenna, and analyzes the radiation principle of slot antenna by discussing the distribution of electric field and current around the slot. The HFSS simulation software is used to build the slot antenna model, calculate the electric field and current distribution, obtain the basic parameters of the slot antenna, and verify the analysis conclusion of the slot antenna principle.

Key words: slot antenna; electric dipole; waveguide; electromagnetic simulation
