A Novel Reconfigurable Antenna for Adaptive IoT Communications in Variable Environments

This paper presents a novel reconfigurable antenna designed to adapt to variable environments and enhance communication reliability for the Internet of Things (loT). The proposed antenna features a flexible reconfigurable cavity structure, allowing adjustment of impedance matching and radiation performance by modifying its height. Experimental results show that the proposed antenna effectively reduces signal degradation and enhances communication quality using its adaptive mechanism in the presence of interference. Notably, the radiation power gain of the antenna along the main lobe direction increased by 2.77 dB under ceramic interference, reducing signal attenuation by 96.52%. This innovative solution offers a low-power option for maintaining stable communication in challenging loT scenarios where environmental interference impacts mobile device performance.
