Low-Profile Harmonic Transponder for IoT Applications

This paper proposes a novel single-layer, low-profile harmonic transponder to be integrated with the printable diodes based on Si particles. The introduced prototype consists of two bowtie dipoles that are directly matched generation element at fundamental 2.45GHz frequency and also corresponding second 4.9GHz frequency. Therefore, antennas T-matching parts can manufactured as separate inlays using single layer-substrate. Besides new prototype, conversion loss (CL) is theoretically experimentally investigated. In this regard, equivalent circuit driven utilized analyze CL performance variations in input power. outperforms state-of-the-art work from printability, size, point views.
