Abstract :
The radiation fields of a biconical horn antenna with different flare angles are derived by the use of both the field of an equivalent Huygens source on the aperture and the field of the infinite biconical horn antenna with TEM wave. Numerical and experimental patterns are presented for the symmetrical biconical horn antennas. Numerical and experimental patterns are also shown for the asymmetrical biconical horn antenna such as discone and a coaxial antenna. From the results obtained, it is evident that the method using both the assumption of TEM wave and the equivalent Huygens source can give accurate predictions of the radiation patterns.<>
