Abstract

This paper simulated and analyzed a circularly polarized (CP) waveguide composite slot radiator at X -band in this paper. According to the radiation principle of the waveguide slot, a composite slot located at the broad wall of a rectangular waveguide, which included a cross-slot and a circular slot, was designed and the specific structure and dimensions were provided. The circularly polarized waveguide cross-slot radiator discussed in this paper was simulated by using the full wave electromagnetic simulation software. The voltage standing wave ratio (VSWR) was lower than 1.2 within the frequency range of from 7.5GHz to 8.5GHz. The simulated axial ratio (AR) at the boresight direction within the discussed frequency range was lower than 3dB. The design and simulation results of circularly polarized waveguide cross-slot radiator in this paper can provide a reference for the practical engineering application.
