抄録

This study proposes a novel microstrip patch antenna for microwave power transfer that functions as a class-F load and DC block. These functions enable a direct connection between an antenna and a power device (field-effect transistor) without using a class-F load circuit and capacitor for a DC block. In numerical simulations of a 2.45-GHz antenna, a reflection coefficient is -21.27 dB at the fundamental frequency, and a reflection coefficient and phase at the 3rd harmonic frequency are -0.99 dB and -1.4°, respectively. The simulated gain is 5.59 dBi at 2.45 GHz.
