Abstract- In this article, a compact, low porfile frequency reconfigurable monopole antenna is proposed. Frequency reconfigurability was achieved by switch which is incorporated between two patches. This antenna resonates at 3.1 GHz when switch is OFF. The proposed design of reconfigurable antenna in the on state of switching element achieved two resonating frequency 2.35 GHz and 5.45 GHz for , which are covering the band of 2.16-2.6 GHz (Wi-Fi) and 5.18-5.81 GHz (WLAN) respectively. The surface current distribution is analyzed at frequencies 2.45, 3.1 and 5.4 GHz. A mathematical equations are developed with the help of current distribution.

Key words- Current distribution, Monopole antenna, Impedance bandwidth.
