Abstract
An air-dielectric stripline is provided which includes top, intermediate and bottom planar dielectric layers spaced from each other in parallel planes with each layer having upper and lower oppositely directed faces. First and second electrically conductive planar ground planes are respectively attached to the lower surface of the top dielectric layer and the upper surface of the bottom dielectric layer. First and second planar dielectric spacer layers are respectively located between the top and intermediate dielectric layers and the intermediate and bottom dielectric layers for maintaining a given spacing therebetween. Each spacer layer has a channel formed therein to thereby define upper and lower air chambers on opposing faces of the intermediate layer. A conductive inner trace is attached to at least one face of the intermediate layer within one of the chambers and is spaced from an associated ground plane by the thickness of a spacer dielectric layer.
