Abstract
The paper describes an improved 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. It is shown that slight discrepancies, frequency dependence and high sidelobe levels for one polarization can be diminished by proposed very simple improved design, which reduces parasitic interferences and improves an electromagnetic susceptibility.
