Patent ID: 8587496

Claim:
A protective cover for an array antenna including a plurality of line arrays, said protective cover comprising: a first, protective outer dielectric layer made of separate sheets of a first dielectric material joined together at seams; a second, middle dielectric layer made of separate sheets of a second dielectric material joined together at seams, said second dielectric material having different characteristics from said first dielectric material; a third, inner layer made of separate sheets of a third dielectric material joined together at seams, said third dielectric material having different characteristics from at least said second dielectric material; and a first broad surface of said middle dielectric layer being juxtaposed with a broad surface of said outer dielectric layer, and a broad surface of said inner layer being juxtaposed with a second broad surface of said middle layer, with each said seams of said outer, middle and inner layers being configured to overlie one of said line arrays of the array antenna.
