Conductor-backed Coplanar Waveguide Research Articles

Analysis and applications of modified coupled coplanar lines

Modified coupled coplanar lines, compatible with the classical and conductor-backed coplanar waveguides, are analysed using the quasistatic and full-wave spectral domain methods. Results of the analysis are utilised for designing a 10 dB directional coupler. Measured isolation of the coupler is higher than 33 dB in the bandwidth up to 5 GHz.

Analysis of conductor-backed coplanar waveguide

The transmission properties of a coplanar waveguide printed on conductor-backed substrates are analysed using the spectral-domain technique. For a fixed substrate thickness, the characteristic impedance and the phase constant may be varied independently by simply adjusting the widths of the centre strip and the slots in the transmission line.
