Analysis of Microstrip Antennas for Wireless Energy Harvesting

Abstract

This document reviews microstrip antennas used in wireless energy transfer and collection systems in microwave bands, based on their technical and structural parameters. The foregoing will allow the identification of outstanding aspects in the use of the different antenna configurations and suggest future lines of research that contribute to the development of this area. For this, a literature review of research articles, papers presented at conferences and symposiums, among others, is carried out which allows knowing the different existing proposals around the subject of study. As a result, it is found that there is a great variety of configurations and techniques for the design of these antennas, with which the radiation pattern can be modified, and the gain improved. It is concluded then that there is no defined construction pattern to obtain the ideal antenna. However, a research perspective is opened to establish and evaluate new structures and materials for the optimization of this type of antennas used in the collection of RF energy as another alternative for the charging of low power devices and the development of the internet of things (IoT) technology.
