Abstract

A simple compact microstrip ratโ€race ring coupler with capacitor loading is presented in this letter. The new coupler not only effectively reduces the occupied area to 15% of the conventional one at 1.0 GHz, but also has high harmonic suppression performance over a wide band. Furthermore, the new structure has only two variable parameters and can be easily designed. The design is validated both by simulation and measurement. ยฉ 2009 Wiley Periodicals, Inc.

## Abstract In this letter, a design of a compact, dualโ€band, ratโ€race coupler is presented. The dualโ€band characteristics are obtained by using two shunt openโ€stubs with the conventional coupler. The proposed design can cover a wide range of frequency ratio of the dual bands within the fabrication
