An ultra-compact (2.5 cm2) rectenna design based on an innovative topology using a coplanar stripline connected to a crossed dipoles antenna array is reported here. Experimental results in the K-band show that a DC power up to 0.9 mW can be harvested on a 0.3 kΩ load by using the proposed compact rectenna for incident power density of 1413 µW/cm2. The targeted application for this rectenna is to power...
This paper addresses the microwave energy harvesting for powering wireless sensors on board of geostationary satellites. The electromagnetic environment existing on such satellites is first investigated and experimental results in K-band demonstrate for the first time the feasibility of such energy harvesting in satellite applications for powering autonomous wireless sensors. Experimental results...
This paper addresses the topics of energy harvesting for powering autonomous wireless sensors on board of geostationary broadcasting satellites. The feasibility of energy harvesting by using thermoelectric modules or rectennas is firstly discussed then the design and the implementation of a rectenna is presented. Experimental results in Ka band demonstrate the feasibility of the use of such rectenna...
