A Dual-Band Reconfigurable Antenna for IoT Devices in Congested Spectrum Environments

Spectral congestion has become critical in modern wireless environments because of the enormous growth of Internet of Things (IoT) devices. Therefore, a compact dual-band reconfigurable antenna capable of real-time frequency agility is designed and implemented using PIN diode–based switching to alle...

description Spectral congestion has become critical in modern wireless environments because of the enormous growth of Internet of Things (IoT) devices. Therefore, a compact dual-band reconfigurable antenna capable of real-time frequency agility is designed and implemented using PIN diode–based switching to alleviate these challenges. The antenna is fabricated on a low-cost FR4 substrate that is amenable to mass deployment of the antenna in the scale of mass market IoT systems. A dual-band engineering proposal for this antenna is made to be efficient in two IoT communication bands widely used today: 2.4 GHz and 5.2 GHz. CST Microwave Studio was used to perform full-wave electromagnetic simulations that were then experimentally validated by VNA. Stable directional radiation patterns are observed through the bands, a measured return loss better than ?18 dB, which confirms robust impedance matching, and a peak gain of 4.2 dBi. In addition, the reconfiguration time of the PIN diode switching mechanism is less than 10 µs, resulting in near-instanta-neous reconfiguration to changing spectrum conditions. These performance characteristics attest to the antenna’s viability in time-sensitive, interference-aware IoT applications such as smart homes, industrial automation, and wearables. The results show how the combi-nation of agile antenna architecture helps improve spectral efficiency, robustness of the links, and communication robustness in the future wireless networks.
