Traveling-Wave Fed Two-Dimensional Phased-Array Antenna for Microwave-Power Transfer

The two-dimensional phased-array antenna for microwave-power transfer is proposed in this work. The antenna designed in small-scale units based on traveling-wave feed technique contributes to scalably expand the antenna aperture. In addition, the number of phase control systems for beam steering is drastically reduced by the proposed feed technique contributes. In this paper, we compare and clear the circuit loss of the parallel and traveling-wave feed line and the limited number of series elements. In addition, we calculate and analyze the beam angle of two-way antenna units in circuit and EM cooperation simulation.
