  • Abstract
    A microstrip rat-race coupler with high isolation and perfect balance is presented. By modifying March´s rat-race coupler with two additional short-circuited stubs, the isolation and the amplitude/phase balance of the proposed coupler improve significantly. The circuit can be easily fabricated on a single-layer substrate using the conventional printed circuit board process.
