Abstract

We have studied a high impedance antenna in order to improve the rectification efficiency for energy harvesting applications. A folded dipole antenna (FDA) with three conductors has high impedance step-up ratio compared with the conventional FDA in the case of small spacing between conductors. The three-conductor FDA using a substrate is designed to obtain high impedance greater than 10kΩ. We also design three-conductor FDAs with 10 kΩ for Cellular and Wi-Fi systems.
