Logarithmic Antennas for Electromagnetic Energy Harvesting Applications

Abstract:

The main objective was the realization and implementation of two designs of spiral and periodic logarithmic antennas, in order to test the feasibility of this technology by storing energy in rechargeable batteries in different environments with the presence of WiFi networks using coaxial cable conductors (copper), optical fiber and an environment with offset antennas. Different existing antennas were investigated and modifications were made to work in the 2.4 GHz band in order to adjust them to our objectives. For this purpose, CST Studio 2018 simulation software was used to perform the designs and review the parameters emitted by each antenna. Finally, the antennas were built based on the proposed design, as well as a voltage multiplier circuit with Schottky diodes and finally, performance tests and validation of the prototype were carried out using the miniVNA Tiny spectrum tester.
