In the paper, we present a dual-band wearable rectenna operating in 900 MHz GSM band and 2.45 GHz ISM band. The rectenna was designed as a multilayer structure to reduce size while having a large enough aperture with a reasonable gain. The antenna was connected to the rectifier by a current probe via a textile substrate. The rectifier was conceived as a voltage doubler to maximize voltage on a load even with a very low received power. The manufactured antenna showed the gain 6.3 dBi at 900 MHz and 2.8 dBi at 2.45 GHz. The rectifier operated from -20 dBm and was measured up to -2 dBm with 19% efficiency for the GSM band and 17% efficiency for the ISM band.
