Array apparatus comprising a dielectric resonator array disposed on a ground layer and individually fed by corresponding signal feeds, thereby providing a corresponding magnetic dipole vector

Abstract:

An array apparatus includes: an electrically conductive ground layer; a plurality of spaced apart dielectric resonators operable at a defined radiation wavelength, the plurality of resonators being spaced apart on an x, y grid having respective x and y dimensions between closest adjacent resonators that are each less than the defined radiation wavelength, each resonator being disposed on and in electrical communication with the ground layer; and, a plurality of spaced apart signal feeds disposed in one-to-one relationship with respective ones of the plurality of resonators. Each signal feed provides a respective electrical signal path through respective ones of the plurality of resonators that defines an orientation of a resulting magnetic dipole vector associated with the corresponding ones of the plurality of resonators; and each pair of closest adjacent ones of the resulting magnetic dipole vectors are oriented parallel with each other but not in linear alignment with each other.
