Micro strip antenna with DGS for Landmine Detection

In this Book, we have studied various Micro strip Antenna (MSA) configurations with mathematical design. In the Literature, various Researchers have been proposed that MSA have low Bandwidth and Gain. To improve Bandwidth and Gain we have designed different DGS shapes keeping patch shape as same before for each design. The simulation has been carried out by using High Frequency Structure Simulator (HFSS) software. For this design dielectric substrate material used is FR4-Epoxy and coaxial feed technique for its simplicity. The performance of these different antenna shapes have been analysed in terms of parameters like Return Loss, Bandwidth, Gain, VSWR, Directivity and Radiation Pattern. It has been found that the Modified double E-Shaped DGS has improved bandwidth and gain over conventional plane ground shape MSA. So we have fabricated the Modified double E-Shaped DGS MSA. The performance parameter such as Directivity, Return loss, VSWR is analysed for simulated and fabricated antenna.
