| Abstract: | A new conformal mapping technique for determining the characteristic impedance of TEM horn antennas is presented. The original work by Carrel 1958], on noncoplanar fin antennas of this type, predicts incorrect impedance values which do not agree with experimental results. The present paper discusses fully the source of the error in Carrel and details the successive mappings involved in the new approach. Verification of the method is provided by experimental results and by comparison with an alternative numerical technique |
