Original Abstract

A tapered slot antenna element capable of reconfiguring its beam direction is presented. As the basic element, a Vivaldi antenna fed by a substrate integrated waveguide is chosen. The Vivaldi antenna is complemented by a parasitic planar array of small metallic patches placed in front of its aperture and by corrugated edges of the Vivaldi antenna’s arms to provide reconfiguration capabilities. The proposed antenna’s beam can be steered in five directions by configuring the interconnections of the parasitic patches and by activation/deactivation of the corrugated edges in the antenna arms. The antenna steers the radiation beam over ±30 ° in E-plane and operates in the frequency band of 6.0–6.5 GHz. The measured gain at 6.25 GHz for 0 °, ±15 °, and ±30 ° beam direction of the antenna with ideal switches, is 8.4 dBi, 7.5 dBi, and 6.7 dBi, respectively.
