概要 The uniform phase planes of the radiated beam in the E- and H-planes are located at different distances from the lens horn aperture due to its asymmetric TE11 mode aperture distribution. A new method by attaching a simple dielectric slab on the lens surface is proposed for matching the distances. The both uniform phase planes are formed 55 mm away from an
antenna aperture with the dielectric slab with thickness of 13 mm for 60 mm antenna aperture at 50 GHz. As a result, the slab improves the phase deviation in the H-plane by 12 degree, and the validity of the proposed method is indicated.
