The paper introduces a multi-band wearable textile patch antenna tailored for operation across the ISM, IoT, C, X, and Ku bands. The antenna features a rectangular patch integrated with U-shaped, circular, and triangular slots to enhance performance. The antenna was crafted on a Jeans substrate with dimensions 0.6 λo × 0.8 λo × 0.01 λo mm3. The antenna has a notable -10 dB impedance bandwidths across 3.15 to 3.25 GHz, 4.04 to 4.17 GHz, 9.67 to 10 GHz, and 10.99 to 12.44GHz that ensure minimal signal loss and reliable performance across the target frequency ranges. The antenna achieves a maximum gain of 7.4 dBi at 12.1 GHz, 3.2 dBi at 9.8 GHz, 5.86 dBi at 4.1 GHz, and 3.58 dBi at 3.2 GHz. The proposed antenna is versatile in terms of frequency bands of operation and applications such as ECG monitoring, Industrial IoT, Wireless Body-Area Network (WBAN) implementations (3.1 GHz), telemetry systems to track the patient in real-time, 5G wireless communication (4.1 GHz), satellite downlinks and radar systems to capture high-resolution images as well as medical imaging and Augmented reality (7.25 GHz). This paper provides a comprehensive overview of the design process for the multi-band wearable textile patch antenna, emphasizing its potential applications and advantages in wearable technology.
