Multiband Rectenna for Microwave Applications Rectenna
, 2016 This paper reports a multiband rectenna (rectifier + antenna) suitable for the electromagnetic energy harvesting of the spill-over loss of microwave antennas placed on board of geostationary satellites. Such rectenna is used for powering autonomous wireless sensors for satellite health monitoring. The topology of the rectenna is presented.

Bow-tie retrodirective rectenna
Electronics Letters, 2006 A novel bow-tie retrodirective rectenna designed at 5.8 GHz is proposed. The new retrodirective rectenna combines a traditional rectenna with a retrodirective array. The new retrodirective rectenna array can automatically steer its main beam towards the power source and hence is not sensitive to the power incident angle changes.
