Abstract

An ultra-wide band (UWB) radio frequency (RF)/optical aperture includes a substrate having a plurality of regions. The plurality of regions may have varying characteristics and properties. In some embodiments, the plurality of regions includes a first region having a first relative dielectric constant and being transparent to signals having a frequency in a first frequency range, a second region contained in the first region and having a second relative dielectric constant and being transparent to signals having a frequency in a second frequency range, and a third region contained within the second region and having a third relative dielectric constant and being transparent to signals having a frequency in a third frequency range.
