A 3-dB multilayer coupler with UC-PBG structure

A novel broadside coupled stripline coupler with a uniplanar compact photonic bandgap (UC-PBG) structure is presented. Construction of the coupler is based on a stripline with two-dimensional periodically etched ground plane. The slow-wave phenomenon has been predicted and observed. Numerical and ex...

Zusammenfassung:	A novel broadside coupled stripline coupler with a uniplanar compact photonic bandgap (UC-PBG) structure is presented. Construction of the coupler is based on a stripline with two-dimensional periodically etched ground plane. The slow-wave phenomenon has been predicted and observed. Numerical and experimental investigations show an enhanced backward coupling effect. The usefulness of both phenomena in the coupler construction has been verified experimentally.
