ABSTRACT:
A millimeter-wave electronic scan, phased array antenna in a slotted dielectric waveguide having a semi-insulating core and at least one semi-conducting epitaxial layer. A controller affixed to the epitaxial layer is used to apply a bias voltage thereby varying the conductivity of the layer and influencing wave propagation in the guide to effect beam scanning.
