Abstract
Radio-frequency (RF) energy harvesting-enabled sensor nodes can alleviate the charging challenges by exploitation of electromagnetic waves in the ambient proximity and contribute to more efficient use of energy resources that is essential to deploy numerous Internet-of-Things (IoT) nodes. An RF spectrum survey was conducted at Nazarbayev University campus to discover potential RF energy sources and their available power levels which revealed four prospective frequency bands. Consequently, two frequencies that demonstrated sufficient power levels and stability for an efficient RF energy harvesting were selected from the analysis of a full week data measurements. Then, the rectangular patch microstrip-fed dual-band antenna operating on those frequencies was designed and fabricated. The proposed meander-line antenna design allowed miniaturization of the effective surface area that is useful for IoT sensor applications. The fabricated prototype and simulation measurements were in good agreement.
