The design and the radiation performance of a novel hybrid Energy Harvesting (EH) and wireless communication system based on a quarter-wave patch antenna with integrated modules for EH applications are documented in this paper. A Thermo-Electric Generator (TEG) and a Solar Cell (SC) are used in order to harvest concurrently thermal and solar energy providing a hybrid EH system. The antenna, with the...
This paper presents a review of existing works and solutions in the field of solar/electromagnetic energy harvesting and wireless power transmission. More specifically, the paper covers: solar/electromagnetic harvesters where solar antenna structures are used to obtain a compact implementation, direct current (dc) combining circuits necessary to combine the outputs of the solar and the electromagnetic...
This work presents the design and implementation of a 927 MHz radio frequency beacon in coplanar waveguide technology, which scavenges through solar energy the power necessary for operation. Starting from a folded-slot antenna topology, a reflection-type oscillator is designed by combining full-wave and nonlinear analyses. Properly placed solar cells and a regulator are used to bias the device by...
