SIR-based miniaturized EBG structure for millimeter-wave isolation improvement applications

A new uni-planar compact electromagnetic bandgap (EBG) structure is presented. The proposed EBG unit-cell is designed based on the stepped-impedance resonator (SIR) technique. Results show that the proposed EBG structure provides a wide frequency bandgap around the 60 GHz band. Moreover, results show that the proposed EBG unit-cell has further… (More)
