Abstract

In this paper, a Gaussian corrugated Profile horn is designed, simulated and compared with a Gaussian Profile horn with flat wall, at central frequency of 94 GHz. The proposed horn antenna consists of a corrugated section(mode converter and phase section) and a Gaussian profile section. The Gaussian Profile horn Antenna provides a smooth transition from waveguide to aperture, which improves matching between antenna and free space. This ensures better matching, better radiation pattern, more bandwidth and increases overall system efficiency. The Corrugated horn also has low edge diffraction, improved pattern symmetry, and reduced transverse polarization, because these corrugations create same boundary conditions for electric and magnetic fields. The symmetry pattern on the E and H orthogonal planes, the broad bandwidth as well as low sidelobes of this designed corrugated Gaussian Profile horn, make it a good representative for use as a feed in Millimeter wave imaging system in W band.
