“…The gain was reduced in both single and dual bands in this work, resulting in a decrease in overall antenna performance. Reference [14] described an ultra-wideband and multiband reconfigurable antenna. The antenna structure employs six switches that allow the antenna to reconfigure across seven different frequency bands, the first of which allows the antenna to operate in the band 3.14-10.6 GHz, and the remaining six configurations are found to cover the various narrow bands.…”

This paper proposes a wide band and multiband frequency reconfigurable antenna that can operate in the UWB, GSM, GPS, 4G LTE, WLAN, and WiMAX bands. The antenna is made up of a trapezoidal-shaped monopole radiator, which was inspired by a rectangular monopole antenna. The ground plane is modified by embedding T and L-shaped slots to notch the desired operating frequency. The proposed antenna can switch to six different frequencies using RF PIN diodes, making it suitable for modern wireless applications. A multilayer frequency selective surface (FSS) reflector is presented to improve the gain of the proposed reconfigurable antenna. The low-profile design achieved a significant increase in gain while retaining the UWB antenna's excellent impedance bandwidth. Because of the use of the FSS reflector, the antenna's average peak gain has increased from 6 to 10.4 dBi. The proposed antenna has a wide switching capability, which validates its unique feasibility for high-speed multiple Internet of Things applications via a common embedded platform under various applications.
