摘要：

In this paper, rectenna techniques for high-efficiency and high-power operation are discussed. At first, harmonic reaction inductive high-impedance antennas implemented with all of RF circuit functionalities in RF-front-end are discussed for highly efficient rectification. Rectifier diodes are directly connected with the antennas without lossy circuit components. With the proposed rectenna topologies, rectification efficiencies of 91.1 % at 2.4 GHz and 92.8 % at 5.8 GHz are achieved on 1 W-class rectifiers. In next, the gated anode diode (GAD) configured with the GaAs enhance-mode pHEMT (E-pHEMT) is discussed for high power rectification. the E-pHEMT GAD has higher current density than that of the GaAs SBD. The developed 5.8 GHz band rectifier MMIC achieved rectification efficiency of 77.9 % at an input power of 5.1 W.
