The crucial role of a decoupling/matching network is demonstrated for the design of a compact 868-MHz double-antenna energy harvester, driving two different rectifiers branches for the efficient powering of a wake-up radio (WUR)-enabled localization node. Two highly-coupled meandered cross-polarized monopoles, located in close proximity, are adopted for orientation-insensitive operations, thus requiring the design of a RF-decoupling and matching network before rectification. The superior performance of the two-element harvester with respect to a standard single-monopole rectenna is experimentally demonstrated in different conditions: it justifies the deployment of the presented tag for the energy autonomy of future generation RFID tags for indoor localization.

Abstract

The crucial role of a decoupling/matching network is demonstrated for the design of a compact 868-MHz double-antenna energy harvester, driving two different rectifiers branches for the efficient powering of a wake-up radio (WUR)-enabled localization node. Two highly-coupled meandered cross-polarized monopoles, located in close proximity, are adopted for orientation-insensitive operations, thus requiring the design of a RF-decoupling and matching network before rectification. The superior performance of the two-element harvester with respect to a standard single-monopole rectenna is experimentally demonstrated in different conditions: it justifies the deployment of the presented tag for the energy autonomy of future generation RFID tags for indoor localization.
