Two-Element Decoupled MIMO Antenna for Energy Harvesting and Backscattering
This work proposes the use of a two-element MIMO antenna decoupled by a neutralization line to combine RF energy harvesting on one port and backscattering on a second port. The use of two coupled antennas allows for improving energy conversion efficiency on one port while communicating at the same time, by modulating the impedance on the second port. The proposed antenna, connected to two independent circuits, operates in the UHF band at 867 MHz. A theoretical study is validated by simulation and practical measurements.
