Left-Handed Coplanar Waveguide

, 2005
This paper proposes a new version of a left-handed coplanar waveguide. The line has a fully uniplanar structure without vias and lumped elements. The series capacitors are represented by interdigital capacitors and the parallel inductors by short ...

Coplanar waveguide amplifier

, 1991
A two-stage microwave amplifier was designed and fabricated with coplanar waveguide (CPW) as the transmission medium of the amplifier. The theory and advantages of CPW are introduced.

Experimental investigations on channelized coplanar waveguide

, 1990
A new variant of coplanar waveguide (CPW) which was termed channelized coplanar waveguide (CCPW) is presented. Measured propagation characteristics for CCPW such as epsilon(eff) and unloaded Q as a function of geometrical parameters and frequency are ...

A comparative study between shielded and open coplanar waveguide discontinuities

, 1993
A comparative study between open and shielded coplanar waveguide (CPW) discontinuities is presented. The space domain integral equation method is used to characterize several discontinuities such as the open-end CPW and CPW series stubs.

Finite Ground Coplanar Waveguide (FGC) Low Loss, Low Coupling 90-Degree Crossover Junctions

, 2002
Microwave and millimeter-wave integrated circuits and RF distribution networks often require two transmission lines to cross over each other. In this paper, experimental measurements and three-dimensional (3-D) finite difference time domain analysis are ...
