Edge-coupled coplanar waveguide bandpass filters

Research output: Contribution to journalArticleScientificpeer-review


Several edge-coupled coplanar waveguide bandpass filters centred at 30 GHz and 60 GHz are designed and fabricated. Filters are measured with and without bond-wires connecting the ground planes in order to see the influence of the unwanted coupled-slotline mode. Filters with bond-wires show remarkably better performance. Furthermore, filters where bond-wires are placed not only at the discontinuities but also in the middle of the couplers show better performance than filters where bond-wires are placed only at the discontinuities.
