Multiple frequency projected artificial magnetic mirror and antenna application thereof

摘要

A multiple frequency projected artificial magnetic mirror (PAMM) includes a plurality of metal traces, a metal backing, and a dielectric material. The plurality of metal traces is on one or more layers of a substrate and the metal backing is on another layer of the substrate. The dielectric material is between the metal backing and the plurality of metal traces, which is electrically coupled to the metal backing. At least some of the plurality of metal traces is of various sizes and of various positioning and spacing to create a distributed inductor-capacitor network having a first frequency band of operation and a second frequency band of operation.

1. A multiple frequency projected artificial magnetic mirror (PAMM) comprises:
a plurality of metal traces on one or more layers of a substrate, the plurality of metal traces comprising a plurality of conductive coils; a metal backing on another layer of the substrate; and a dielectric material between the metal backing and the plurality of metal traces, wherein the plurality of metal traces is electrically coupled to the metal backing and at least some of the plurality of metal traces are of various sizes and of various positioning and spacing to create a distributed inductor-capacitor network having at least a first frequency band of operation and a second frequency band of operation; and wherein, for one or more of the at least first or second frequency bands of operation, the plurality of conductive coils reflect electromagnetic energy forming a projected magnetic surface effectively forming a dish antenna above the plurality metal traces.
