4.1. Rectenna Measurement
- Measuring the gain of the standard broadband horn antenna: a vector network analyzer is used to measure the insertion loss of the coaxial line which is used to connect the DRA array and the rectifier circuit in the experiment;
- Add a 3 dB coupler behind the signal generator; one port is connected to the power probe, and the other port is connected to the broadband horn. On the premise of meeting the dual frequency far-field conditions, the distance between the broadband horn and the proposed DRA array is fixed as r; measure the input power at the broadband horn;
- The receiving power at 2.45 GHz and 5.8 GHz is calculated according to the Friis transmission equation;
- The voltage across the load resistance is measured with a multimeter, and the efficiency of the rectenna is calculated.
