8–12-GHz beam-shaping/steering phased antenna array system using SIW fed nonplanar director Yagi-Uda antenna

This paper presents a novel beam shaping/steering phase array system using substrate integrated waveguide (SIW) fed Yagi-Uda array antenna. This structure employs an integrated waveguide structure Lens as a beam shaping network (BSN). The proposed microwave lens is Rotman type integrated lens in substrate. A prototype phase array system is designed with 7 beam ports, 9 array ports, and 8 dummy ports. A 10 GHz SIW-fed Yagi-Uda antenna is proposed with nonplanar director element as radiating elements with scanning capability over (-24°, +24°). Throughout this paper, the design process of the proposed 8-12 GHz phase array system has been demonstrated in details.
