Abstract :
A novel uni-planar electromagnetic band gap (EBG) structure incorporated with spiral shape capacitor and meandered line inductor (SC-ML-EBG) is presented. This structure significantly enlarges the equivalent capacitance between neighboring elements, as well as increases the equivalent inductance. So, it becomes even more compact in size. A comparison has been carried out between this new structure and the conventional UC-EBG structure. The simulation result shows that its center bandgap frequency depresses over 50% than that of the conventional UC-EBG in the same period of the lattice.
