Investigations On Split Ring Resonator For GPR Antenna
A new Microwave frequency range resonator for Ground Penetrating Radar (GPR) antenna is proposed in this paper. An approach based on the effects of the properties of meta material in Split Ring Resonators (SRRs) is used to design a SRR for GPR. The variation of effective permeability and permittivity of Split Ring Resonator (SRR) by change of configuration is reported in this research. Each left handed metamaterial (LHM) unit cell was constructed by modifying a square Split Ring Resonator (SRR), resulting in negative permeability and permittivity with a stable negative refractive index. Investigations are made on shift in resonant frequency due to change in dimensions of the ring, material of the ring.
