This paper presents a wearable antenna that is low cost, low profile, and flexible for Wireless Body Area Network (WBAN) applications. The antenna is multi-band: 2.4 GHz (Medical Body Area Network (MBAN)), 2.45 GHz (international & domestic industrial, scientific, and medical (ISM) band), 3.5 GHz (WiMAX), and 5.2 GHz (WLAN). Microstrip radiating patch is hexagonal and is on low-cost photo paper substrate with a defected ground plane to improve impedance matching and bandwidth. The antenna is 30 × 40 mm², and has a wide operational bandwidth of 3 GHz (2.30–5.30 GHz). Performance analysis shows radiation efficiency (greater than 91%) and that gain remains consistent across frequency bands with limited impairment from bending radius. Specific Absorption Rate (SAR) was completed, to assure safety if anticipated usage with humans. Deemed suitable for wearable healthcare monitoring, and Internet of Things (IoT) applications, and will provide a low-cost solution for the communications sector, this study provide potential avenue for next-generation wireless communication systems.
