Automated design of corrugated conical horns for dual-band applications

A highly efficient full-wave model and CAD of conical corrugated horns is discussed. The capabilities of the CAD tools are demonstrated by the design of dual-hand horn operating over the 20 - 21.5 and 29.5 - 31.5 GHz bands. A comparison of the designed horn characteristics obtained with the Kirchhoff-Huygens approach and Wiener-Hopf technique is presented.
