Abstract(in English) | In this report, power characteristics of the 5.8 GHz band 5 W rectenna are discussed. The rectenna is consisting of the gated anode diode (GAD) configured with the GaAs E-pHEMT for improving power characteristics. At first, a measured DC characteristic of the GAD and its saturation is demonstrated. In the saturation region, a differential resistance of the GAD is increased and makes degradation of rectification efficiency. In the discussions, GAD currents’ waveforms with different gate widths are demonstrated, and their influences on power characteristics are discussed. As a result, gate width of 1.2 mm is designed for the rectenna. In experimental investigation, the rectenna consisting of a GaAs rectenna IC and a high-impedance antenna is fabricated on the aluminum nitride substrate that has low thermal resistivity as metal plates. Measured rectification efficiency of 85.2 % at input power of 5 W is obtained. |
