Abstract: We gave topology and preparation process of a 2.45 GHz and 5.8 GHz flexible wearable monopole dualband antenna based on polydimethylsiloxane (PDMS) flexible substrate and organosilicone conductive silver adhesive. The structure of the flexible dualband antenna was optimized and the performances of the antenna were characterized. The results show that the experimental results are in good agreement with simulation results. The return losses of the dualband antenna at the center frequency of 2.45 GHz and 5.8 GHz are -26 dB and -28 dB, respectively.
