Abstract

The applications of choked Gaussian horn antennas with extremely low sidelobe compact antenna design are discussed. The bowl-shaped horn under investigation was designed for practical narrowband application where design goal was to minimize spillover energy beyond 8.7° edge-of-coverage. First sidelobe level of about -36 dB was achieved, which was a compromise with rapid rolloff. It is observed that the Gaussian-profiled horn antennas provide good 'Gaussian pattern characteristics'. The tolerance of ∓0. 0004λc in mode generator resulted in sidelobes.
