Abstract: A rectenna is equivalent to a series circuit of a DC power and a load. Equivalent models of series and parallel of rectenna arrays are proposed, so that the relationship of the optimum loads and the element numbers for the series and parallel rectenna arrays are obtained. Using a rectenna element with low power density applications, the two-element parallel array is analyzed with ADS software. The two-element arrays in series and in parallel are measured. Simulated and measured results of the parallel array and measured results of the series array are approximately in accordance with their equivalent models, showing effectiveness of the equivalent models. Suggestions are given for designing large rectenna arrays.
