Wideband Isosceles Trapezoid Dipole Array for Electromagnetic Energy Harvesting
Abstract
In this paper, a novel energy harvesting dipole array based on two printed asymmetric off-center fed isosceles trapezoid dipoles is proposed. The dipole array not only has extremely high energy conversion efficiency, but also has wideband characteristics due to the isosceles trapezoidal electromagnetic structure. In order to verify the feasibility of design, the dipole cell and array are numerical simulated with ANSYS HFSS successively. For the alternating current (ac) conversion, the bandwidth with over 80% efficiency of cell reaches approximately 1 GHz, while the bandwidth with over 90% efficiency also approaches 0.6 GHz. Besides, when cells are expanded to an array, the array’s performance can be further improved. The experimental results are in line with expectations.
