%X A novel triple-band uni-planar electromagnetic bandgap (UC-EBG) structure is proposed in this paper. This EBG structure can be considered as distorted uni-planar compact-EBG (DUC-EBG) which is connected together by the meandered line inductor. Split ring resonators (SRR) are embedded in four pad corners and two L-shaped slots are etched at the central pad. The proposed EBG structure is modelled in three equivalent circuits. By using in-house developed computational code based on the FDTD method, simulated results of dispersion diagrams are presented by complete triple-bandgap. The central frequency of the bandgaps can be reduced to the lower region without increasing the size of the EBG cell. Moreover, an array of 4กม5 EBG cells was simulated, fabricated and measured to verify the bandgap characteristic through the transmission coefficient S21. This proposed EBG can be used for multi-band applications, such as dual/triple antennas.
