Polarized rotation retrodirective array

The invention discloses a polarized rotation retrodirective array which is composed of a doubly fed square patch, a phase-conjugating mixer and a local oscillator power divider. The polarized rotation retrodirective array can be used in the microwave millimeter wave communication system, radio frequency identification and wireless energy transmission. The advantage is that the polarized rotation retrodirective array can realize backtrace of the orthogonally polarized wave of the wave in any direction, the phase-conjugating circuit is simple in structure, the local oscillation suppression is high, the cost is low and the processing cycle is short. 本发明公开了种极化旋转方向回溯阵列，由双馈方形贴片、相位共轭混频器、本振功分器构成。本发明可用于微波毫米波通信系统、射频识别、无线能量传输中。其优点是可以对任意方向来波回溯其正交极化波、相位共轭电路结构简易、本振抑制度高、低成本、加工周期快。
