Abstract:

A multi-layer microwave corrugated printed circuit board is provided. In one embodiment, the invention relates to a method for interconnecting components of a corrugated printed circuit board, the components including a first flexible layer having a first signal line on a surface of the first flexible layer and a second flexible layer having a second signal line on a surface of the second flexible layer, the method including forming at least one first hole in the first flexible layer, forming a conductive pad on the second flexible layer, forming at least one second hole in a non-conductive adhesive layer, aligning the at least one second hole with the at least one first hole and the conductive pad, bonding the first flexible layer and the second flexible layer, with the non-conductive adhesive layer disposed there between, and filling the at least one first hole and the at least one second hole with a conductive paste to electrically couple the first signal line with the second signal line.

International Classification:

H01Q 21/24

US Classification:

343810, 343848

Abstract:

Provided herein are devices, systems and techniques for establishing a coincident-phased dual polarization array aperture enabling a wide scan capability, while also presenting a bandwidth of at least about 40%. Radiating elements of such an array include a first ground plane extending between lower and upper edges and a first radiating element positioned above the upper edge of the first ground plane. The array elements also include a second ground plane extending between respective lower and upper edges and disposed substantially orthogonal to the first ground plane. A second radiating element is positioned above the upper edge of the second ground plane, such that the first and second radiating elements have different polarizations.Parallel ground planes of adjacent antenna elements of an array of like elements enhance array performance by providing isolation between such radiating elements and backplane ground by way of a phenomenon generally known as waveguide-below-cutoff.
