Abstract: A dual-polarized rectenna with wide load characteristics is presented in this paper, which can be effectively applied in microwave power transmission. The rectenna is mainly composed of the transmission line based resistance compression network(RCN), matching circuit, Schottky diode and harmonic rejection circuit. The transmission line based resistance compression circuit consists of two short-circuiting branch lines, which can reduce the variation of input impedance in the load range from 500 Ω to 3500 Ω and reduce the influence of the load on the matching, thus improving the rectification efficiency. ADS2020 software simulation results show that the bipolar rectifier circuit achieves a maximum RF-DC conversion efficiency of 81% at a frequency of 2. 45 GHz and the input power of both ends is 10 dBm. In the load range of 1000-3000 Ω, rectification efficiency are higher than 60%; in only one end of the input power, the load rectification efficiency is still greater than 50%. Additionally, the measured results agree with the simulation ones very well, which further verifies the feasibility of our design. The measured results show that the rectenna can still output stable DC voltage when the antenna attitude or the terminated load changes in a wide range. The design has the characteristics of simple structure, easy manufacturing, dual polarization, wide load, etc. It has some practical application value for the development of wireless power supply technology in wireless sensing nodes and internet of things.
