A pattern reconfigurable rectenna, consisting of a pattern reconfigurable receiving antenna and a low-/medium-power rectifying circuit, is proposed for microwave power transmission with multiple transmitting antennas. By controlling the states of p-i-n switch groups, the receiving antenna can work at one omni-directional mode and eight directional modes with flattened wide main beams for the arbitrary direction of incoming waves. In order to achieve good impedance matching at different modes, where the received power fluctuates severely, a complex impedance compression network (CICN) is introduced to the rectifying circuit. Since the proposed rectenna has a versatile structure, it can be used for multiple transmitting antennas in conformity with the incoming waves’ direction.

具有全向/定向辐射模式的模式可重构整流天线，用于具有多个发射天线的 MPT

提出了一种由方向图可重构接收天线和低/中功率整流电路组成的方向图可重构整流天线，用于多发射天线的微波功率传输。通过控制引脚开关组的状态，接收天线可以工作在一种全向模式和八种定向模式，具有平坦的宽主波束，适用于任意方向的入射波。为了在接收功率剧烈波动的不同模式下实现良好的阻抗匹配，在整流电路中引入了复阻抗压缩网络（CICN）。由于所提出的整流天线具有通用结构，因此可以根据入射波的方向用于多个发射天线。
