Dual-Polarized Wearable Antenna/Rectenna for Full-Duplex and MIMO Simultaneous Wireless Information and Power Transfer (SWIPT)

Owing to the mobility of a wearable antenna and unpredictable body-centric communications environment, dual-polarization antennas are essential for both energy harvesting. This paper presents dual-polarized four-port textile antenna/rectenna simultaneous wireless information power transfer (SWIPT) applications. The proposed utilizes dual ports off-body communication harvesting from horizontal vertical polarizations. maintains 100 MHz bandwidth with an S 11 under -10 dB around 2.4 GHz in presence absence human body, at least 10 small-signal large-signal isolation between all ports. 70-88% measured total efficiency 8.4-9.6 dBi gain various on-phantom positions across mutual coupling is co-polarized rectenna/antenna ports, -16 orthogonally-polarized A high RF DC peak conversion over 70% (±5%) achieved broadside pattern. Based on antenna's performance, SWIPT microstrip can be adopted full-duplex MIMO applications, significantly reducing complexity future battery-free networks non-wearable
