A multi frequency fresenel lens using a perforated dielectric
A novel technique for the design of multi-frequency capable Fresnel lenses is investigated. The frequency dependant nature of a zoned Fresnel lens is considered, and a solution of the lens equations which allows multiple-band operation is developed. The technique is then further augmented with the use of perforated dielectric material to yield a low cost and light weight lens structure. The combination of these two approaches allows for greater versatility in the use of Fresnel lenses for SATCOM terminals.
