This paper addresses the microwave energy harvesting on board of geostationary satellites for health satellite monitoring. To prove the feasibility of such a concept, we investigated the electromagnetic environment existing on antenna panels. Based on established cartographic maps, three designs of rectennas are proposed. Measured dc powers ranging from(More)

This paper addresses an ultra-compact (2.8 cm<sup>2</sup>) and wide bandwidth rectenna operating in the extended Ku-band. Experimental results demonstrate that the proposed rectenna can harvest a DC power ranging from 0.125 mW to 1.43 mW for frequencies between 14.5 GHz to 19.5 GHz and for resistive loads between 250 &#x03A9; and 4 k&#x03A9;. A maximum(More)
