Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
65 words
A method of assembling a multi-dielectric laminate comprising the steps of: providing a ground plane; bonding a first dielectric material of a given dielectric constant and a second dielectric material of another given dielectric constant onto the ground plane having a boundary therebetween; and bonding a common conductor over said dielectric materials to provide a constant impedance over the boundary between the two dielectric materials.
Claim 2
Independent Claim
65 words
A method of assembling a multi-dielectric laminate comprising the steps of: providing a ground plane; bonding a first dielectric material of a given dielectric constant and a second dielectric material of another given dielectric constant onto the ground plane having a boundary therebetween; and bonding a common conductor over said dielectric materials to provide a constant impedance over the boundary between the two dielectric materials.
Claim 3
Dependent Claim
