Abstract
A microwave coupler including a first transmission line having one or more strip sections, and a second transmission line having one or more strip sections respectively associated with corresponding sections of the first transmission so as to form associated pairs of coupled strip sections. The associated coupled strip sections are substantially uniformly separated from each other and non-coplanar. Dielectric material dielectrically separates the associated strip sections of the first and second transmission lines.

A microwave coupler comprising:
- a first conductive transmission line having one or more strip sections;
- a second conductive transmission line having one or more strip sections respectively associated with the sections of said first tranmission line, wherein associated strip sections are substantially uniformly separated from each other and non-coplanar and thereby coupled;
- dielectric means for dielectrically separating associated strip sections of said first and second conductive transmission lines, wherein said dielectric means comprises a dielectric layer having first and second sides:
