A novel multi-resonator using rectangular slotted complementary split ring resonator (CSRR) on planar transmission line is proposed for the design of chipless RFID tag. The chipless design consists of 4 rings resonator which etched on the back of the substrate and is connected to 50 ohm planar transmission line. Each resonator enables to code in four different allocations (00, 01, 10, 11) with bandwidth...
This paper presents the design of multiband reconfigurable antenna using metamaterial Electromagnetic Band Gap (EBG) unit cells. The two EBG unit cells were position underneath the feeding of the antenna. By implementing the band gap characteristics of the EBG, the antenna can be reconfigured at various multiband frequencies simultaneously. The EBG band gap characteristics of the EBG unit cells were...
A wideband metamaterial antenna employing SRR loading is presented. Two designs were simulated, fabricated and measured. The bandwidth enhancement is achieved by loading SRR resonator onto a conventional monopole antenna. The SRR excited a lower resonance frequency mode which matches with the resonance frequency of the monopole antenna thereby extending the overall impedance bandwidth from 26% to...
