Abstract
Abstract Radio frequency array antenna structures and methods for fabricating such structures are disclosed wherein a plurality of radio frequency circuits forming the radiating face of an array antenna and a corporate feed are formed on one or more relatively flexible dielectric sheets and then bonded to a suitable core material to form a complete array structure which is light weight, inexpensive and structurally sound.

Claim 1
Independent Claim
125 words
The method of forming a conformal array antenna comprising the steps of: a. forming a plurality of array modules, each one being formed by: i. etching simultaneously on one surface of a flexible dielectric sheet, an array of radiating elements, a ground plane for such elements, a corporate feed network for such elements and a portion of a parallel plate lens coupled to the feed network; ii. folding such dielectric sheet around a stiffener including: disposing the plurality of radiating elements in a first plane, and, positioning the ground plane behind the radiating elements in a plane orthogonal to the first plane; and iii. bonding such folded dielectric sheet to such stiffener; and b. arranging the plurality of array modules around a predetermined conformal surface.
