Abstract :
The paper describes full-wave numerical simulations for design of hoghorn, which is formed by a sectoral horn, flaring in only one plane, with parabolic cylinder. Hoghorns possess high efficiencies, low levels of back lobe radiations, good impedance matching and reasonable radiation pattern stabilities. However, near-by sidelobes are relatively higher. The numerical results are compared with the measurements.
