A high-gain Bull’s-Eye leaky-wave horn antenna
working at 77 GHz with sinusoidal profile has been designed,
fabricated, and experimentally measured. The influence of the
number of periods on the gain and beamwidth is numerically
investigated. Experimental measurements show a high gain of
28.9 dB, with low sidelobe level and a very narrow beamwidth in
good agreement with results obtained from simulations.
