Abstract: A flexible stretchable antenna working at 2.45 GHz was designed based on flexible conductive fabric, and the influence of different stretchable strains on the performance and radiation properties of the proposed flexible fabric antenna were studied. The simulation and measurement results show that the simulated and measured values of return loss are -40,-26 dB respectively at central frequency of 2.45 GHz, and the simulated and measured gain patterns have good consistency at the central frequency.

Key words: flexible antenna, fabric antenna, stretchable, conductive fabric
