Abstract
Abstract A substrate for mounting electronic devices is provided with a capacitive coupler as an interconnecting means. The coupler comprises two partially co-extensive conductors surrounded by a shield. The substrate is made from a plurality of superimposed layers, each layer consisting of a dielectric, or a conductive material, or strips of conductive material separated by the dielectric to form a preselected profile.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
207 words
A method of forming a substrate for supporting electronic components and having a microwave coupler formed therein, comprising the steps of: providing a first layer of conductive material; sequentially forming a plurality of pairs of spaced conductive strips in a plurality of layers overlaying said first layer, each strip of each pair of conductive strips being in electrical contact with the first conductive layer and with a corresponding strip of each other pair, corresponding strips of each pair overlaying each other to form a pair of spaced walls having a channel therebetween; providing dielectric material in portions of each of said plurality of layers not occupied by conductive strips; forming a second conductive layer on the plurality of layers, whereby the first and second layers and the plurality of pairs of conductive strips define a shielded space in said channel; and forming two spaced conductive strips in one or more of said plurality of layers and within said shielded space, each of said spaced conductive strips being spaced from said first and second layers, being spaced from the pairs of spaced conductive strips, and being formed with a coupling portion, said coupling portions being spaced a predetermined amount to provide a desired coupling for said microwave coupler.
