Claims13
An antenna structure, comprising:
- a substrate forming a waveguide structure having a plurality of layers, comprising;
- a first dielectric layer;
- a second dielectric layer;
- a slotted conductive layer positioned between the first and second layers;
- and
- an array of radiating elements positioned proximate the second layer,
- wherein the waveguide structure is configured for propagating electromagnetic waves along the waveguide structure;
- and
- a beam-tilting means coupled to the array of radiating elements, adapted to control a reactance of the array of radiating elements to correspond to a plurality of dielectric materials of varying dielectric constants,
- wherein the waveguide structure is reconfigurable.
