Abstract
A broadside 90° microwave coupler is composed of three metal layers in a homogeneous dielectric media. The coupler is constructed in a multi-layer configuration with two conductor strips arranged on top of each other so as to be electro-magnetically coupled. A ground plane formed with a third metal layer below the coupled conductor strips is opened so that it is separated from the conductor strips by a gap. The two conductor strips are fully embedded into the dielectric layer. The characteristic physical dimensions of the coupler are determined to achieve the desired coupling coefficient while maintaining low reflection, high isolation and phase balance at the output ports of the coupler.
