Abstract
A wideband matching surface (600) for a dielectric lens antenna (100) is formed from a first dielectric layer (602) (e.g., Rexolite™) characterized by a first refractive index and a second dielectric layer (604) characterized by a second refractive index supporting the first dielectric layer (602). The first and second dielectric layers (602, 604) are formed by periodically removing material from the dielectric layers according to fill factors determined by: The material may, for example, be periodically removed along two axes (702, 704) to form squares (706, 708), thereby provided reflected power attenuation for both horizontally and vertically polarized electromagnetic waves.
