  • Abstract
    A new coplanar waveguide (CPW)-to-slotline transition that is uniplanar and bridgeless is presented. The transition consists of a CPW cross and CPW stubs in which both the even and odd modes are utilised. Based on this transition a uniplanar bridgeless CPW balun has been designed and fabricated. The fabricated balun has 1 dB insertion loss, 0.8 dB maximum amplitude imbalance, 4° maximum phase imbalance and 56% fractional bandwidth. Measurements are in a good agreement with simulations.
