چکیده
A novel wearable button antenna sensor is proposed for the concept of simultaneous wireless information and power transfer (SWIPT). This integrates two working modes information, respectively, optimizes efficiency. An omni-directional radiation pattern achieved in 3.5 GHz World Interoperability Microwave Access (WiMAX) band to support on-body communications, while a circularly polarized broadside obtained 5 local area networks (WLAN) harvest power. The measured −10 dB return loss bandwidths are 4.0% (3.47–3.61 GHz) lower band, 25.0% (4.51–5.80 higher respectively. artificial magnetic conductor (AMC) structure with wideband characteristics applied obtain low-profile design increase stability sensor. high efficiency over 80% whole observed. specific absorption rate (SAR) below 0.509 W/kg at 3.55 GHz, 0.0532 5.5 which much than European standard threshold 2 W/kg. All these make designed suitable transmission off-body energy harvesting. has been prototyped. Simulations measurements agree well, proving validity new concept.
