This work presents an electronically scanning leaky wave antenna based on liquid crystals. The antenna provides a continuous scanning at fixed frequency with a single voltage control. The radiating part is constituted by a parallel plate waveguide filled by liquid crystals with gradually modulated, electrically small slots etched on the upper wall. The feeding network is realized through a pillbox network. The concept is first validated through the realization and experimental characterization of a static antenna prototype.
