Abstract

Dual-band frequency reconfigurable antennas have gained vital attention in advanced wireless communication due to their capability to operate efficiently at two distinct frequency bands. This work introduces a dual-band microstrip antenna with frequency reconfigurable features specifically designed for 5G and WLAN applications. It is developed by modifying a conventional antenna's feed line, resonating patch, and ground structure. The proposed antenna resonates at 3.43 and 5.9 GHz due to a folded arm resonator and radiating patch, respectively. Further, a PIN diode is used between T-shaped arms and a rectangular patch to achieve frequency reconfiguration. When the diode is OFF state, the antenna is resonating with dualband operation at 3.43 GHz(3.23-3.58 GHz) and 5.9 GHz(5.47- 6.24 GHz). Meanwhile, during the ON state of the diode, it only resonates at 5.85 GHz(5.49-6.15 GHz). The designed antenna offers a peak gain of 2.53 dBi at 3.43 GHz and 3.95 dBi at 5.9 GHz, demonstrating effective operation at both targeted frequency bands.
