Ultra-Wide Band Rectenna Design with Discone Antenna and Rectifier with High Impedance Inductor

This paper presents an ultra-wideband (UWB) rectenna using discone based antenna and rectifier with a high impedance inductor for wireless power transfer. The discone antenna has a well-known wideband frequency coverage and the rectifier using a high impedance inductor removes the matching network requirements and enables the rectenna to operate in ultra-wideband. The UWB rectenna covers the frequency range from 0.65 GHz to 5 GHz and has 16% of efficiency when operating in 2.45 GHz and receiving RF power of 5 dBm. Therefore, the rectenna works on a large frequency range not requiring modifications in order to be used in several applications.
