Abstract :
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.
