In this paper, a novel reconfigurable antenna for wireless IoT operations is proposed.The antenna dimensions of 27.5 x 8 x 0.8 mm 3 and fabricated on the FR-4 dielectric substrate with a hlaf ground plane. The desined antenna works in the frequency range of WiMAX, I.S.M. and X band (3.2-3.8 GHz, 5.2-6.9 GHz, and 7.1-10 GHz). The frequencies can be reconfigured by one P.I.N. diode BAR64-03W, and antenna attained the gain ranging of 2.84-3.26 dBi. The proposed antenna has bidirectional radiation at higher-frequency bands and unidirectional at lower frequency bands. The suggested frequency reconfigurable antenna has a radiation efficiency of 96.12% at 3.5 GHz and 94.34% at 5.9 GHz,92.02% at 8.4 GHz in ON state.
