Textile UWB antenna performance for healthcare monitoring system

A unique metamaterial-based UWB band notched textile antenna for Body Area Network (BAN) is created in this paper, with an operational frequency range of 3–11 GHz, spanning the Ultra Wide Band (UWB) band (3.1–10.6 GHz). Using the textile material Jeans, which has a permittivity of 1.67, the antenna’s size is lowered. To enhance the impedance bandwidth, the ground plane is made of partially conductive material and is rectangular. The hexagonal slot is used to increase the electric field dispersion along the borders of the hexagonal slot, which improves bandwidth. The gain of the UWB of the antenna maximum is obtained at 7.52 dB and minimum is obtained at 5.25 dB. The VSWR of the UWB of the antenna maximum is obtained at 1.92 and minimum is obtained at 1.45. The fabrication uses a Denim substrate with a thickness of 1 mm and a microstrip feed. The designed antenna is investigated for its return loss and gain characteristics.
