Reconfigurable radiation from a W-band trough waveguide antenna: trade-offs in impedance and radiation from tapered MEMS-based perturbations

This work examines tapered, variable-length, MEMS-based perturbations for fixed frequency beam steering of a W-band trough waveguide antenna. Tapered (non-rectangular) perturbation geometries are utilized to reduce the impedance mismatch due to phase accumulation while scanning through broadside (wh...
