Reconfigurable Band switching Antenna for millimeter wave Applications

This work gives, a latest frequency reconfigurable antenna that is proposed for Bluetooth, WiMAX, and higher WLAN applications with acceptable reconfigurable radiations. The performance of this structure was examined experimentally using a nonflexible FR4 structure which is simulated using HFSS simulator. The proposed antenna uses a T-shaped strip with ON or OFF states at desired frequency operations and has dimensions of an E-shaped slot that are optimal that vary with the ground layer. The prototype is small and light, with switchable millimeter wave applications and frequencies that cover 5G cellular telephony in 24- to 30-GHz bands, as well as UWB operations.
