A Reconfigurable F shaped Antenna design for GSM, WLAN and WiMAX Applications

The demand for miniaturized, affordable, wide-band and multiband antennas has increased as communication technology has developed over the last decade. An innovative frequency-configurable F-shaped antenna for use in the GSM, WLAN, and WiMAX frequency bands is presented in this study. The antenna is fabricated on low cost FR-4 substrate and the vector network analyzer (VNA) is used to test the fabricated antenna. The results from the fabricated antenna are in good matching with those from simulations. The antenna may be made resonant at three modes of 1.8 GHz, 2.45 GHz, and 5.5 GHz frequencies respectively, by adding shorts at the suitable locations throughout the slot and offering suitably constructed matching stubs. By opening the door for more developments in wireless communication systems, this innovative frequency reconfigurable antenna design makes a significant contribution to the sector.
