本文提出了一种新型的叠置差分整流天线，并对其特性进行了实验研究。该天线采用差分操作，可以有效地将射频功率转换为直流功率。当接收功率密度低至0.041W/m时，转换效率可达44.1%(2)。该天线结构简单，易于实现大规模天线阵列。与单个整流天线相比，直流连接的整流天线阵列具有几乎相同的转换效率和入射角特性。
In this communication, a novel stacked differential rectenna is proposed and its characteristics are experimentally investigated. The proposed rectenna can effectively convert RF power to dc due to its differential operation. The conversion efficiency of 44.1% was obtained when the received power density was as low as 0.041W/m(2). The proposed rectenna can easily achieve large-scale rectenna arrays effectively using its simple structure. The rectenna array with DC connection provides almost the same conversion efficiency and incident angle characteristics in comparison with a single rectenna.
