Investigations on Metamaterial based Log Periodic Dipole Antenna
In this paper, the application of metamaterial to the accustomed log periodic dipole antenna (LPDA) for ground penetrating radar is presented. The metamaterial based Split Ring Resonator (SRR) is loaded with dipole in accustomed LPDA. The proposed antenna is printed on FR4 substrate with length and width 81.9 x 65.5mm. The antenna has 68% size reduction as compared to accustomed antenna. The simulation results show that the proposed antenna has wide bandwidth and high gain, which is suitable for Ground Penetrating Radar (GPR) applications.
