S-Shaped Hexaband Frequency Reconfigurable Antenna

Background: This paper presents S shaped frequency reconfigurable antenna which gives six operating bands. Objective: The size of proposed antenna is 26×12 mm2. The FR4 substrate having thickness of 1.6 mm is used for this antenna. Methods: The proposed antenna resonates at six different frequencies i.e. at 2.76 GHz, at 2.98 GHz, at 4 GHz, at 4.6 GHz, at 4.96 GHz and at 5.28 GHz depending upon the ON/OFF states of PIN diodes. The lumped RLC elements are used in HFSS simulation in order to reconfigure the frequency of antenna. Results: For switching, PIN diode are used in fabricated antenna for frequency reconfiguration to validate the simulated results. The compact size of proposed antenna is suitable for recent communication devices such as laptop, mobile phone and other electronics instruments. Conclusion: The proposed antenna shows good matching in the simulated and measured results.
