Wearable antennas play an important role in transmitting signals wirelessly in body-worn\nsystems, helping body-worn applications to achieve real-time monitoring and improving the working\nefficiency as well as the life quality of the users. Over conventional antenna types, ultra wideband\n(UWB) antennas have advantages of very large operating bandwidth, low power consumption,\nand high data transmission speed, therefore, they become of great interest for body-worn applications.\nOne of the strategies for making the antenna comfortable to wear is replacing the conventional rigid\nprinted circuit board with textile materials in the manufacturing process. In this study, a novel\nthree-dimensional woven fabric integrated UWB antenna was proposed and fabricated with pure\ntextile materials. The antenna electromagnetic properties were simulated and measured and its\nproperties under bending were investigated. The antenna operated in a wide bandwidth from 2.7 to\n13 GHz with the proper radiation pattern and gain value. At the same time, the antenna performance\nunder bending varied in a reasonable range indicating that the antenna is prospectively applied\non the curved surfaces of the human body. Additionally, the current distribution of the antenna\nshowed that different conductive parts had different current densities indicating the uniqueness of\nthe three-dimensional textile-based antenna.
