Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents the design of the lens antenna array dedicated to THz applications operated at 300 GHz. The proposed design antenna is based on replacing a single-large-aperture lens into N small-aperture lens elements with the focus to diameter ratio (F/D) of a lens antenna unchanged, the overall thickness of the proposed antenna is reduced by N times to achieve high gain beam antenna and offers further reductions in mass and height of lens array in applications. Correspondingly, antenna height reduces by 40% in the proposed 2x2 lens array comparing to single-large-aperture lens antenna without performance degradation. Besides, lens shaping techniques have also been applied in this design to study the performance of the lens antenna array. Plano-convex and concave-convex lenses shaped are used in the design. The simulation results of the concave-convex lens antenna array produced gain at 34 dBi, narrow radiated beamwidth for both boresight-axis at E-plane and H-plane, and reliable sidelobe levels with more than -15dB.
