Abstract :
A high-impedance wideband folded dipole antenna (FDA) has been designed for energy harvesting applications. High impedance is necessary for producing high efficiency rectennas. An impedance of over 300 Ω can be achieved by FDAs due to the impedance step-up function. The wideband design is introduced theoretically using an equivalent circuit for the FDA. A bandwidth over 20% with a characteristic impedance of 350 Ω was achieved. Measurements of the fabricated antenna are compared with the results of simulations and the high-impedance wideband design is verified.
