- Abstract
Reconfigurable antennas are pivotal in advancing the versatility of modern wireless communication devices, allowing operation across diverse frequency bands, polarizations, and radiation patterns. This study introduces a tri-band frequency reconfigurable planar monopole antenna that leverages a shortened metal ground plane and a 1.6 mm thick FR-4 substrate to enhance its adaptability in multi-band wireless applications. Our innovative design utilizes optical switching to transition between dual-band and single-band operational modes: Enabling Wi-Fi at 2.4 GHz and WLAN at 5.65 GHz in the dual-band mode, and WiMAX at 3.5 GHz in the single-band mode when the optical switch is toggled off. The antenna's configuration not only fulfills the demanding multi-frequency requirements of contemporary portable devices like laptops, PDAs, and smartphones but also caters to specific applications in safety and rescue operations due to its compact, lowprofile, and lightweight design. Performance evaluations demonstrate robust functionality with optimal frequency reconfigurability, highlighted by a VSWR below 2 across all operational bands, making it a prime candidate for future scalable wireless systems.
