This paper presents an efficient spiral rectenna to be used for radio frequency energy harvesting application. This rectenna is simple, low cost and an efficient design exhibiting a power conversion efficiency of 85–88% at different conditions. The unique feature of the proposed model is, it eliminates the need for an external matching circuit thus reducing the complexity of the design, cost and is compact. Also, it has been analyzed that this rectenna exhibits good performance at different load conditions, input power levels and with different models of schottky diodes.
