Abstract
A transparent dielectric-core antenna surrounded by patterned metallic metasurfaces. The patterned metallic metasurface acts as a conductive medium for surface current to flow and efficiently radiate fields driven by a power source. Furthermore, the patterned metallic metasurface can strongly reduce the electrical presence of the dielectric-core to realize a radio-transparent antenna to nearby systems at any desired frequency band while still maintaining good radiation and matching properties. Such an antenna concept may be applied to a variety of geometries.
