TL;DR: In this article, the design information for coplanar-waveguide directional couplers has been calculated using quasi-static zeroth-order approximations, and experimental results on a 10-dB directional coupler designed from these calculations have shown reasonably good agreement with predictions.
Abstract: Design information for coplanar-waveguide directional couplers has been calculated using quasi-static zeroth-order approximations. Experimental results on a 10-dB directional coupler designed from these calculations have shown reasonably good agreement with predictions. The smaller difference in even- and odd-mode velocity in a coplanar-waveguide directional coupler leads to better directivity and better performance than a microstrip directional coupler.

TL;DR: A planar balanced circuit suitable for the realization of broadband microwave mixers and frequency multipliers, in integrated circuit form, was described in this article, where a hybrid junction was formed by joining a slot transmission line and a coplanar transmission line.
Abstract: A new type of planar balanced circuit, suitable for the realization of broadband microwave mixers and frequency multipliers, in integrated circuit form, was described in September 1969. In this circuit, a hybrid junction was formed by joining a slot transmission line and a coplanar transmission line. Four diodes were connected at the junction in the form of a ring to realize a balanced mixer.

TL;DR: In this article, a surface strip transmission line with loss characteristics similar to those of microstrip lines of the same width and characteristic impedance has been proposed and some preliminary Q measurement results obtained on coplanar waveguides are reported.
Abstract: Some preliminary Q measurement results obtained on coplanar waveguides are reported. The novel surface strip transmission lines have loss characteristics similar to those of microstrip lines of the same width and characteristic impedance.
