摘要：

A stripline forward-wave directional coupler is proposed using periodical double multi-via mushroom structures and short-circuited branch lines in this paper. By adding the short-circuited branch lines to the coupled lines and the patch of the upper or lower mushroom structure, the operating bandwidth is enhanced for the unit cell design. The even/odd mode phase difference of one unit cell is located within 20 similar to 30 degrees from 6.1 to 6.7 GHz with an acceptable even/odd mode Bloch impedance mismatching. Finally, a prototype is fabricated by multi-layer printed circuit broad technology and measured. The agreement is achieved between the simulated and measured results.
