Abstract :
In this paper, design, analytical analysis and numerical analysis of beam-steering possibilities of the planar transmission line loaded with microelectromechanical systems (MEMS) capacitors and stub inductors is presented. First, the design and analysis of a single unit cell comprising antenna structure is carried out. By stacking certain number of these unit cells leaky-wave structure is obtained, which is then analyzed. As a result, effective beam-steering structure (controlled by MEMS capacitance variation) is obtained.
