Abstract

This paper designed a circularly polarized (CP) horn antenna working at X frequency band in this paper. The stepped septum polarizer (SP) was used to convert the linear polarization into circular polarization for the discussed square horn antenna. The circularly polarized horn antenna designed in this paper was simulated by using the full wave electromagnetic simulation software, and the specific structure and parameters were provided. The voltage standing wave ratio (VSWR) was lower than 2 within the frequency range of from 8GHz to 8.25GHz. The simulated axial ratio (AR) at the boresight direction at frequency 8GHz was about 3dB. The simulated gains of the designed antenna were about higher than 17dBi within the frequency range of 8GHz to 8.2GHz. The design and simulation results of circularly polarized horn antenna in this paper can provide a reference for the practical engineering application.
