Abstract :
The rapid evolution of 5G communication demands compact, efficient antennas for wearable systems. Wearable devices require lightweight and low-profile antennas. Dual-band operation supports multiple 5G frequency bands. This research focuses on designing an ultra-compact dual-band antenna. The antenna targets 5G sub-6 GHz and mm Wave frequency bands. Miniaturization is achieved through geometry optimization. The design integrates fractal or slot techniques for size reduction. The antenna is fabricated on a flexible substrate. Simulations are performed using EM solvers like CST or HFSS. Return loss (S11) is evaluated for both frequency bands. Radiation patterns are analysed for wearable performance. The antenna shows stable gain across both bands. Specific absorption rate (SAR) compliance is evaluated. Design achieves low profile suitable for body-worn devices. Mechanical robustness is considered for bending scenarios. Dual-band performance supports 5G IoT connectivity. High efficiency i
