Design of novel tanh/linear dual profiled smooth horn with low sidelobes

A novel smooth horn with tanh/linear dual profile is proposed and the low sidelobe level is achieved. Measured results demonstrate that sidelobes <−37 dB can be achieved on the principal cuts of designed radiation pattern at 92–97 GHz. Also, the measurements are in accordance with the simulated results. It is shown that low sidelobe level can be obtained by the proposed horn geometry without tremendous amounts of time and money designing and manufacturing.
