Abstract
The present invention is directed to a coupler structure that includes a first port, a second port, a third port, and a fourth port. L first transmission line layers are disposed in the structure. Each first transmission line layer includes a first transmission line conforming to a predetermined geometric configuration. The first transmission line is disposed on a first dielectric material between the first port and the second port. L is an integer. M second transmission line layers are disposed in alternating layers with the L first transmission line layers to form a total of N transmission line layers within the structure. M and N are integers and N is greater than or equal to three. Each second transmission line layer includes a second transmission line substantially conforming to the predetermined geometric configuration. The second transmission line is disposed on a second dielectric material between the third port and the fourth port. Each second transmission line is disposed in a predetermined position relative to a corresponding first transmission line within the structure.
