The revolution in communication has led to a significant increase in the demand for textile and flexible antennae for biomedical and wearable applications. Wearable devices are considered the next generation of communications due to their wide application, which requires compact, lightweight, and low power consumption. These devices can monitor patients' daily activities, such as blood pressure, heart rate, and temperature. However, there are challenges in creating compact wearable and flexible antennas due to bending and rolling effects on efficiency, gain, and resonant frequency. In body-centric applications, the effective capacitance of the antenna is affected by coupling with the resonant frequency, which significantly impacts its efficiency and gain. Therefore, it is crucial to study the effect of the body on the effectiveness of wearable and flexible antennae. Non-conductive textile materials like felt, nylon, leather, denim, and washed cotton are used as substrate materials to create low-weight wearable antennas with robust rolling and bending behavior. Multi-band antennas are popular because they can transmit frequencies from a single antenna in various applications, including human-to-human and human-to-network communication. Metamaterial (MTM) antennas can be an effective choice for wearable antennas as they reduce antenna size, increase gain, and reduce body effects by eliminating back radiation. The design and development of metamaterial-based textile multi-band antennas are proposed, which can be effectively used for biomedical applications with body proximity and in wearable applications.
