Abstract

This work presents the design, manufacturing, and measurement of a miniaturized circularly polarized ultrawideband Archimedean spiral antenna that operates from 0.3 GHz to 16 GHz. It acts as a radiofrequency harvester, capturing the energy spectrum in the bands of interest (FM, DTT, LTE‐800, GSM‐900, GSM‐1800, LTE‐2100, WiFi, LTE‐2600 and WiMAX). A prototype of the Archimedean spiral has been manufactured and characterized in the laboratory, and a comparison of the harvested power with respect to other also manufactured baseline 2.4 GHz patch antennas has been carried out in two different locations: inside and outside the laboratory. These results prove that hundreds of microwatts can be acquired in a normal situation, without the spiral pointing directly at a prefixed source.
