A novel Wilkinson power divider with predictable performance at K and Ka-band

Multi-port microstrip power dividers, used in array antenna applications, frequently utilize the Wilkinson design. The standard asymmetrical Wilkinson design has problems at frequencies beyond X-band, due to coupling between the output branches. A novel, modified design is presented. Its operation can be easily and accurately modeled. Its successful operation is demonstrated using measurements from a 2:1 Ka-band power divider, and a 14-way K-band power combiner.<
