A groundbreaking antenna designed for integration into smart clothing has been developed, offering seamless 5G and Wi-Fi connectivity. This miniature, bendable antenna, capable of transmitting and receiving data from both 5G and Wi-Fi networks, opens up exciting possibilities for the future of wearable technology.
Scientists have developed a tiny, bendable antenna capable of 5G and Wi-Fi connectivity, designed specifically for smart clothing. This 2-port multiple-input-multiple-output (MIMO) antenna is integrated into a textile and has been engineered for use close to the human body. Its small size (24 x 24mm) allows it to be discreetly hidden in a shirt pocket. The antenna can be fabricated on various materials, including denim, cotton, felt, and even silk.
The tested version, made from denim, can be flexed horizontally and vertically without performance degradation. It boasts sufficient gain for normal use while remaining safe for proximity to the body. The antenna's ability to utilize dual-band Sub-6 5G and Wi-Fi frequencies—3.5GHz 5G and 5.2GHz Wi-Fi—sets it apart from other recent single-band wearable antennas and those lacking MIMO connectivity. This dual-band functionality is crucial as 5G and 6G networks expand, with MIMO antennas playing a pivotal role in reliable communication due to their low path losses, high channel capacities, high data rates, and extended communication range without requiring additional power input.This breakthrough in connected clothing holds immense potential for various applications, including the military and space exploration. However, its relevance to everyday life lies in its use in health and sports. The dual-band antenna enables sensors within clothing to collect and transmit health data without relying on a smartphone or smartwatch, eliminating the need to carry extra devices and enhancing versatility. Furthermore, an antenna integrated into smart clothing could facilitate connectivity with other wearables, paving the way for truly smart clothing with integrated flexible screens. Notably, the antenna's Specific Absorption Rate (SAR) has been assessed, demonstrating that it absorbs minimal power from the body and falls well below the minimum acceptable levels for safety. While this development is exciting, it remains a research project and is not yet commercially available for use in clothing. However, it represents a significant step towards realizing the potential of smart clothing
