Novel reduced-size lumped-element coplanar waveguide-to-slotline transitions are proposed, using planar parallel LC circuits to replace the λ/4 transformer structure. A simple equivalent-circuit model is also established, from which various lumped-element transition structures are carefully examined. Specifically, a 'ring-type L' lumped-element transition with a 1.8:1 bandwidth and 1/12 the size of conventional ones is achieved.
