Microstrip Line with a Novel Broadband PBG Structure

A new scalariform cross (a cross with a square in the middle) slot structure is proposed for a broadband photonic band-gap (PBG) microstrip line. Compared to other PBG structures of simple geometries, wider frequency stopbands, greater than 40 percent ...

Photonic band-gap (PBG) structures were initially proposed in the optical component field. In the microwave field, PBG periodic structures suppress the propagation of electromagnetic waves whose frequencies are within certain bands. They allow shifting the rejected frequency band by simply changing the geometry parameters of the PBG element or...
