Reduction in Return Loss of a Novel Reconfigurable Antenna at 3.4 GHz by FR4 Substrate Using Double PIN Diodes

Abstract

Aim: The main objective of the project is to reduce the return loss of a reconfigurable antenna at 3.4 GHz by using FR4 substrate with Double PIN diodes. Materials and Methods: Two diode configurations of single PIN diode and Four diodes configuration of double PIN diodes are used with a sample size of 6. Results: From HFSS simulation software Return Loss(-30.2dB) and VSWR (1.10) of Reconfigurable Monopole antenna is improved by FR4 substrate using Double PIN diodes. Attained significance ratio(P=0.05) in statistical analysis. Conclusion: Double PIN diode of a reconfigurable Monopole antenna performs well (Return Loss is reduced by -7dB) when compared with a single PIN diode of a reconfigurable Monopole antenna.
