Abstract

A uniplanar wide-band magic-T circuit using an asymmetric coplanar-stripline (ACPS) or a coupler waveguide (CPW) ring circuit is proposed. Both types of structure exhibit a uniplanar configuration which reduces the circuit complexity and manufacturing cost. A phase-reverse section is built in the E-arm branch of the circuits to obtain the function of a magic-T operation. The ACPS- and CPW-ring magic-T couplers have measured band-widths of 4.4 and 4.6 GHz, respectively, with acceptable amplitude and phase imbalances.
