摘要

A high gain dual-circularly-polarized hyperbolic profiled corrugated horn antenna with low sidelobes and cross-polarizations levels is presented in this paper. The antenna consist of a high gain corrugated horn, a groove polarizer and an orthomode transducer (OMT). The simulation results show that good impedance matching, axial ratio and realized gain are obtained within the frequencies of interest ranging from 7.9 GHz to 8.5 GHz.
