Highly efficient rectenna is demanded for wireless power transfer systems. We develop high-impedance wire-loop antennas in order to obtain high rectification efficiency in mm-wave band. We propose magnetic coupling with excited loop and wire so that the wire has role of efficient radiator. In the paper, simulations of a wire-loop antenna on an Alumina substrate are conducted. To get higher impedance and efficiency, we analyze the effects of antenna parameters on the antenna characteristics. Consequently, we designed the antenna with high resistance of 1280.6 $\Omega$ and radiation efficiency of 95.1%.
