An Inventive DGS-Based Textile Antenna with Semi-Circular Ring with Triangular Cut for Healthcare Applications

This paper introduces a novel health monitoring textile antenna integrated with Defected Ground Structure (DGS). The latest antenna has a semi-circular ring with an isosceles triangle cut that is optimized for impedance matching, bandwidth and radiation efficiency. The textile materials used in the antenna offer flexibility, light weight and easy integration into bodyworn devices suitable for continuous health-monitoring applications. We have justified and confirmed through detailed simulations and experimental verifications the efficient operation of the designed antenna over the intended frequency ranges, providing essential wireless communication capabilities that are required for healthcare monitoring purposes. The outcomes stress the prospective of the antenna for incorporation in clever textiles paving the way to progress wearable healthcare technology. The performance of the proposed DGS-based textile antenna was evaluated by analyzing its return loss across a frequency range of 3.67 to 7.96 GHz with the wide bandwidth of 73.83%.
