Abstract

In this paper, a compact reconfigurable monopole antenna is proposed working at three different frequencies depending upon the condition of the optical switch. The proposed reconfigurable antenna in the state of ON switchhas resonant frequencies of 2.45 GHz and 5.4 GHz covering the band of 1.8-2.7 GHz (Wi-Fi) and 5.26-5.99 GHz (WLAN) respectively. The same antenna during OFF state of switch operates only at 3 GHz covering the band of 2.49-3.84 GHz. The proposed multiband reconfigurable antenna is designed and fabricated on an FR-4 substrate having relative permittivity of 4.4, loss tangent of 0.02 and thickness of 1.6 mm. The antenna is fabricated and tested in the laboratory to validate the simulated results. A good agreement between the simulated and measured results is obtained in term of radiation pattern and return loss. The performance of the reconfigurable antenna under both states of switch is examined on the basis of the antenna parameters such as return loss, radiation pattern and gain.
