Abstract

A radar absorbing material comprising multiple layers integrated to form a thin flexible and light weight structure. The material includes a substrate disposed thereon antenna elements that are relatively loaded to enable one to construct a device in relatively small and thin size. The broad handling of the device is carried out by multi-layering concepts in which different size antenna patterns are multi-layered with each layer designed to absorb frequencies in s specified range. The antenna elements are selected for their intrinsic broadband properties and to preferably be polarization insensitive.
