通过在圆锥喇叭内壁加磁介质涂层的方法，成功地设计了具有低副瓣、低交叉极化和方向图对称的喇叭天线。该磁介质涂层既是良导电体，又是良导磁体。通过选择合适的喇叭张角，该喇叭天线与波纹喇叭性能相同，而且比波纹喇叭设计简单。 The horn antenna with low side lobe, low cross-polarization and the symmetry of the pattern has been successfully designed by applying the magnetic coating on the inner wall of the cone horn. The magnetic dielectric coating is both a good conductor and a good conductor. By selecting the appropriate horn angle, the horn antenna and ripple horn performance is the same, but also simpler than the corrugated horn design.
