Claims
- 1. A process of fabricating a low weight, multi-element directional antenna comprising the steps in sequence of:
- affixing a metallic foil forming an array of parasitic elements to a surface of a first planar dielectric substrate formed of a foam material;
- affixing a preformed printed circuit board to the surface of said first dielectric substrate, to overlie the array in part, said printed circuit board comprising a second planar dielectric substrate which is smaller in plan than said first dielectric substrate, said second dielectric substrate having a ground plane reflector on one side thereof and a driven element and phasing means comprising a hybrid junction on the other side thereof, and aligning said printed circuit board so that it is coplanar to the surface of said first dielectric substrate with the ground plane reflector facing the first dielectric substrate.
- 2. A process as claimed in claim 1, and including the step of forming said array by stamping or etching.
- 3. A process as claimed in claim 1, and including the step of forming said array by additive techniques.
- 4. A process as claimed in claim 1, and including the step of forming said array by subtractive techniques.
- 5. A process as claimed in claim 1, wherein said metallic foil is affixed to said dielectric substrate by an adhesive.
- 6. A process as claimed in claim 1, and including the step of forming said ground plane reflector and said phasing means by subtractive techniques.
- 7. A process as claimed in claim 1, and including the step of forming said ground plane reflector and said phasing means by additive techniques.
- 8. A process as claimed in claim 1, and including the step of forming said metallic foil by laminating a metal foil to a dielectric film.
