Simulation study of a 4 – 28 GHz double ridged conical horn antenna

The design and simulation-based analysis of a 4-28 GHz double ridged conical horn is presented in this work. While the horn offers a VSWR of less than 1.6 over the entire bandwidth, it also exhibits desirable radiation patterns. More importantly, as per the simulation study, the ridged conical horn gives neat radiation and gain patterns throughout the band unlike the conventional ridged pyramidal horns whose patterns deteriorate at higher frequencies.
