Abstract
Novel directional antennas are disclosed which utilize plas-monic surfaces (PS) that include or present an array of closely-spaced parasitic antennas, which may be referred to herein as 'parasitic arrays' or fractal plasmonic arrays (FPAs). These plasmonic surfaces represent improved parasitic directional antennas relative to prior techniques and apparatus. Substrates can be used which are transparent and/or translucent.
