Abstract
We propose to design high directivity, high level couplers using coplanar waveguide technology. This allows geometrical parameters to be chosen to design 3 dB couplers while limiting the difference between the phase velocities of the normal modes in order to obtain higher directivity. A 40% bandwidth, 30 dB directivity 3 dB coupler is achieved.<>
