Broadside-coupled coplanar waveguides and their end-coupled band-pass filter applications Academic Article uri icon


  • New broadside-coupled coplanar waveguides, suitable for applications requiring wide bandwidths, tight couplings, and large mode effective-dielectric-constant ratios, are presented. Their analysis and investigation are described. Simple equations relating the per-unit-length capacitances of the C-and -modes and the per-unit-length capacitance matrices of the coupled structures to those obtained when applying even-and odd-symmetric voltages are also derived. New broadside end-coupled band-pass filters have been developed at X-band (812 GHz) with less than 1.5 and 1.0 dB passband insertion losses using the proposed four-ground-plane and two-ground-plane coplanar waveguide structures, respectively. Good agreement between the experimental results and those predicted theoretically was also observed. 1992 IEEE
