Design of a Compact Dual-Band and Dual-Mode Wearable Antenna for WBAN Applications
This paper presents a novel design of a compact dual-band dual-mode wearable antenna. The antenna is fed through a single coaxial feed probe, which excites TM<sub>01</sub> and TM<sub>11</sub> modes at 2.45 GHz and 5.8 GHz, respectively. These modes exhibit distinct radiation characteristics. The omnidirectional TM<sub>01</sub> mode at 2.45 GHz is suitable for on-body communication, while the directional TM<sub>11</sub> mode at 5.8 GHz is more appropriate for off-body communication. The antenna prototype was fabricated and measured. The measured performance is consistent with the simulations. Additionally, further simulations and measurements were conducted to verify the interactions between the proposed antenna and the human body. The results demonstrate that the proposed antenna exhibits significant potential as a candidate for wireless body area network (WBAN) communications.
