A new method, with branches having an equivalent series inductance using defected ground structure, is proposed for size reduction and harmonic suppression of branch-line coupler. The proposed structure is 35% of the conventional branch-line coupler at 1 GHz and the measured third harmonic signal is less than −30 dB. © 2006 Wiley Periodicals, Inc.
