| Annotation | This paper presents a novel multiband omnidirectional antenna optimized for Internet of Things (IoT) applications, ensuring reliable and seamless connectivity across multiple frequency bands and orientations. The proposed antenna employs a compact planar fractal bow-tie radiator array, which provides highly efficient spectrum coverage for both sub-7 GHz and millimeter-wave (mmWave) 5G bands. Its omnidirectional radiation pattern is achieved through a fractal geometry-based array configuration, enabling robust connectivity in all directions. The antenna effectively covers targeted IoT frequency bands at 4-4.6 GHz, 5.1-5.3 GHz, and 6.3-6.7 GHz, ensuring stable and high-performance wireless communication. With compact dimensions of 100 mm 40 mm 1.6 mm, the antenna maintains a return loss better than 10 dB across operational bands and a peak gain ranging between 4 and 8 dB. These characteristics contribute to consistent omnidirectional performance, making the antenna a reliable solution for IoT networks in diverse environments. Furthermore, its low-cost fabrication process and space-efficient design enhance its suitability for seamless integration into scalable IoT deployments. The design also ensures minimal interference and efficient spectrum utilization, which are critical for modern wireless systems. The strong agreement between simulated and measured results validates the antenna’s performance, reinforcing its potential for large-scale manufacturing and deployment in next-generation IoT-enabled applications, including smart cities and industrial automation. |
