Analysis and design of DGS by inserting of a active element PIN diode in slot patch

Abstract

In this work, a rectangle is formed one side of substrate material i.e. FR-4/glass epoxy, PIN diode and slot integrated on ground patch,on the basis of reflection coefficient S11, a re-configurability characteristics is found. Using the PIN diode the electrical length of slot can be changed when the PIN diode is in ON / OFF position has more than one resonant frequency. Patch antenna is compatible with characteristics use as dual band antenna under ON condition of PIN diode in wireless communication, these frequencies are 6.45 Ghz and 9.7 GHz. OFF conditions 6.46GHz and 9.8GHz.all the parameters remains same during the current distribution. A reconfigurable property of patch antenna is found.
