In order to enhance the adaptability of wireless devices across diverse applications,it becomes imperative for an antenna to embody a multitude of functionalities,including the capacity to dynamically reconfigure the operating frequency,polarization mode,and radiation *** paper introduces a frequency-reconfigurable antenna that incorporates an L-U shaped slot band with a Split-Ring Resonator(SRR).Fabricated on a 1.2 mm low-cost FR4 substrate using a partially grounded design approach,which measures 40 x 35 *** manipulating the bias states of the two PIN diodes,the radiation element current and field distributions can be altered,resulting in reconfigurable bands spanning 2.45 GHz,3.3 GHz,4.5 GHz,7.4GHz,and 9.4 GHz,with an expansive ultra-wide bandwidth(UWB) of 4230 *** antenna design caters to a range of wireless applications,including WLAN(Wireless Local Area Network),WiMAX(Worldwide Interoperability for Microwave Access),Remote Radio,and X-band Satellite *** meticulous simulation optimization,four reconfiguration scenarios are thoroughly examined by presenting and analyzing the simulation results.
