| Abstract(in English) | Dielectric lens antennas are suited for use as antennas in 300 GHz band because they can easily achieve high gain with low feeding loss. A homogeneous spherical lens antenna essentially performs no scan loss due to its spherical symmetry. Wide scan angle can be expected in the design of multi-beam antenna by using spherical homogeneous dielectric lens antenna. In the design of a multi-beam antenna, it is necessary to design the lens and the primary radiator considering the crossover levels between adjacent beams. In this paper, we optimize the distance between a primary radiator and a spherical lens. Furthermore, by using a tapered aperture horn with a partially reduced aperture width, the spacing between primary radiators is reduced. By employing the proposed aperture horns as primary radiators, it is demonstrated that a close beam pitch for multi-beam spherical lens antennas attained high crossover level over 28 dBi within $pm$30$circ$ angular range. |
