Printed Ultra-Wideband Cardioid Monopole Antenna for Energy Harvesting Application

A compact ultra-wideband monopole Cardioid antenna based on fractal geometry for energy harvesting applications is proposed in this paper. The antenna is designed for energy harvesting in WIMAX, WLAN and satellite communications ranges. The performance is achieved using the cardioid shaped radiating element on low-cost FR4 substrate.Simulated results show that antenna have S11 value-10dB in range from 4 GHz to 30 GHz covering almost all SHF band (3-30 GHz). In addition, the gain is up to 5 dBi and efficiency up to 80%. This antenna is very simple for manufacturing, has ultra-wide band, high gain and efficiency and therefore is suitable to use in energy harvesting applications. Proposed antenna performance are simulated in time domain based CST solver.
