Conformal antenna with dielectric lens

Abstract:

A conformal antenna having dielectric lenses disposed over the antenna elements is disclosed. The antenna comprises a circuit board having a composite dielectric. The composite dielectric includes an array of a plurality of antenna elements disposed on the top surface and a conductive ground plane disposed on the bottom surface. A conductor extends from an antenna input through the composite dielectric, the conductor forming microstrip with the bottom surface conductive ground plane. The top surface of the composite dielectric further comprises at least one dielectric lens, each dielectric lens disposed over only one antenna element of at least a subset of the plurality of antenna elements.
