摘　　要：提出了一种新型高效微带与共面带线混合结构的整流天线,由接收面积大、增益高的矩形微带贴片构成接收天线,然后过渡到具有平行结构的共面带线,以便摆放二极管和电容,避免了钻孔,试验表明接收系统整流转换效率达到了78.2%,验证了设计的可行性。A novel high-efficiency rectifying antenna （rectenna） is presented by using a mixed structure of microstrip and coplanar striplines. The receiving antenna is constructed by a rectangle microstrip patch with high-gain and large receiving area, and then a micrstrip is converted into a coplanar striplines with parallel structure so that to deposit the diode and capacitance and to avoide a bore. The experimental results show that the conversion efficiency reaches 78.2%, and the feasibility of the mixed structure is validated.
