Abstract： According to the improvement requirement of existing rectangular waveguide polarization conversion technology， a rectangular waveguide polarization conversion method based on linear polarization electromagnetic wave polarization conversion theory is proposed， and a new rectangular waveguide polarization conversion device is designed. The 3D electromagnetic simulation model is established by using HFSS software. Compared with the traditional polarization conversion device， the simulation results show that the design has many advantages， such as low standing wave ratio， low insertion loss， simple structure， small volume and so on.

Keywords： rectangular waveguide; polarization conversion; Voltage Standing Wave Ratio （VSWR）; device design; HFSS simulation
