A Waveguide to Unenclosed Coplanar Waveguide Transition
IEEE Transactions on Microwave Theory and Techniques, 2010A transition from rectangular waveguide to unenclosed coplanar waveguide (CPW) is designed and tested at W -band. Full-wave finite-element analysis is applied to the design and optimization trends are shown for the critical parameters. A stepped-impedance filter suppresses a parasitic mode, which is generated as the circuit emerges from the waveguide ...

Coplanar-Waveguide Directional Couplers
IEEE Transactions on Microwave Theory and Techniques, 1970Design 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.

A novel PBG coplanar waveguide
IEEE Microwave and Wireless Components Letters, 2001A novel coplanar waveguide with photonic bandgap structure is proposed and is implemented by etching holes in the ground plane with an open connected with the gap between strip line and ground plane. Simulation and measurement results show the existence of a bandgap.

1993 IEEE MTT-S International Microwave Symposium Digest, 1993
Examples of highpass, lowpass, and bandpass filters realized in coplanar waveguide are presented. The design is based on distributed circuit theory and is improved by extensive modeling of discontinuities. Equivalent circuits for these are presented, together with some design data.

Role of complex modes in coplanar‐waveguide‐to‐coplanar‐waveguide discontinuity calculations
Microwave and Optical Technology Letters, 1991AbstractThe existence of complex modes in the lossless symmetrical shielded coplanar waveguide is demonstrated. Complex modes are found to occur only within a range of frequency and structural parameters. It is shown that exclusion of these modes in the analysis of coplanar waveguide discontinuities can cause the imput reflection and transmission ...

Analysis of coplanar waveguide-to-coplanar stripline transitions
IEEE Transactions on Microwave Theory and Techniques, 2000The coplanar waveguide (CPW)-to-coplanar stripline (CPS) transition is analyzed theoretically and experimentally in this paper. To characterize this transition in the lower frequency band, a simple equivalent-circuit model that consists of uniform and nonuniform transmission lines is established.

UWB Coplanar Waveguide Octagonal Antenna
Wireless Personal Communications, 2015This paper concerns the design of a new ultra-wideband antenna with an octagonal configuration and reduced size. The prototype has been simulated and designed. It has shown a permissible agreement between simulations and measures and an operation of ultra-wideband from 2.38 to 14 GHz (142 %) for wireless applications.
