摘要：

This study presents a dual-hand 180 degrees hybrid coupler with a filter response. The hybrid coupler consisting of four coupled stepped-impedance resonators has a second-order Chebyshev filter response. A 2.45/5.8-611z filtering 180 degrees hybrid coupler has been designed and fabricated on a Rogers R04003C substrate for WLAN applications. The insertion loss 1/vertical bar S-21 vertical bar is about 3+1.2/3+1.5 dB, and isolation are better than 24 dB. The proposed design can be used for dual-band and multifunctional applications.
