A Novel Compact Split Ring Slotted Electromagnetic Bandgap Structure for Microstrip Patch Antenna Performance Enhancement
A novel design of an Electromagnetic Band Gap (EBG) structure based on the Uniplanar Compact EBG (UCEBG) concept is proposed in this paper. The structure is realized by inserting split-ring slots inside two reversely connected rectangular patches, which is known as a Split-Ring Slotted Electromagnetic Band Gap (SRS-EBG) structure. The bandgap properties of the EBG structure are examined by the suspended microstrip line and Finite Element Methods (FEMs). The achieved bandgaps have widths of 4.3 (59.31%) and 5.16GHz (38.88%), which are centered at 7 and 13GHz, respectively.
