Abstract :
A new uniplanar coplanar waveguide (CPW) magic-T and a reverse-phase CPW hybrid-ring coupler were developed. Both circuits provide good amplitude and phase characteristics over a broad bandwidth. Experimental results showed that the magic-T has one octave bandwidth from 2 to 4 GHz and the hybrid-ring coupler has a 60% bandwidth from 2 to 3.6 GHz.<>
