英文摘要：

In order to improve the wearing comfort of body centric wireless network, a flexible textile antenna based on graphene/PANI/PDMS composites and fabric flexible substrate was proposed in this paper for 2. 45 GHz. The geometry and dimensions of the proposed antenna were illustrated and optimized; and the measured reflection coefficient and -10 dB bandwidth achieved -22. 6 dB and 165 MHz,respectively. The radiating properties were also characterized and the measured results showed a good correlation with the simulated results. Meanwhile, the SAR under different distances was also studied based on phantom model in HFSS with three-layer tissue. The proposed antenna and preparation methods provide a feasible solution to the design of flexible antenna for wearable wireless communication system.
