Patent attributes
A dielectric resonator antenna (DRA) array having an array feeding network and a parasitic patch array made up of individual antenna elements is provided with a dielectric lens made from a single piece of dielectric material in the form of a generally planar sheet. The sheet may be substantially coextensive with the DRA array so as to cover all of the antenna elements. The single piece of dielectric material has a plurality of dielectric portions defined by a plurality of holes through the sheet. Each dielectric portion may be positioned over one of the antenna elements. Adjacent dielectric portions are connected to each other along connecting edge portions thereof, and a single hole is defined through the sheet between connecting edge portions of a group of mutually adjacent dielectric portions.
