2017 International Applied Computational Electromagnetics Society Symposium - Italy (ACES), 2017
For powering small wireless IoT nodes, compact, efficient rectifying antennas have been realized. A first design for 868 and 915 MHz is described. Based on the lessons learned, a new design for 2.45 GHz is realized that is a factor 13 smaller in size.

Differential Mode Rectenna Array
Proceedings of the 2012 IEEE International Symposium on Antennas and Propagation, 2012This paper reports “Differential Mode Rectenna Array” for the wireless microwave power transmission. A novel differential mode rectenna unit which has antenna array integrated with a rectifying circuit and feed circuit is proposed. Two differential mode rectenna units are partly overlapped in the rectenna array. The advantages of this differential mode

Rectenna design for passive RFID transponders
2007 European Microwave Conference, 2007This work emphasises rectenna design issues of passive RFID transponders for 868/915-MHz and 2.45-GHz ISM bands. The characterisation of transponder chip takes into account the impact of connecting antenna to rectifier by flip-chip bonding process. Proposed experimental way allows finding chip impedance exactly as it seen by antenna.

Rectifying antennas (Rectennas) have been fabricated with zero bias n- and p-Schottky barrier diodes and planar antenna structures on high-resistivity silicon substrates. The rectenna is manufactured by silicon monolithic millimeter wave integrated circuit (SIMMWIC) technology. The maximum sensitivity of the rectenna is 153 mV/(mWcm?2) at 94 GHz.

5.8-GHz stacked differential mode rectenna suitable for large-scale rectenna arrays
2013 Asia-Pacific Microwave Conference Proceedings (APMC), 2013In this paper, a novel stacked differential mode rectenna is proposed and its characteristics are experimentally evaluated. The proposed rectenna operates in a differential mode. Therefore, the proposed rectenna can effectively rectify microwave power even under low power environments.

5.8-GHz Series/Parallel Connected Rectenna Array Using Expandable Differential Rectenna Units
IEEE Transactions on Antennas and Propagation, 2013This communication demonstrates series and/or parallel connection of the differential rectenna units. The differential rectenna unit provides high expandability of rectenna arrays due to its balanced structure. The proposed rectenna array produces higher voltage and/or more current by the series and/or parallel connection of the rectenna units.

Transparent rectenna and rectenna array for RF energy harvesting at 2.45 GHz
The 8th European Conference on Antennas and Propagation (EuCAP 2014), 2014This paper deals with the design, realization and measurements of transparent single-element rectenna and 6-elements rectenna array at 2.45 GHz. The proposed circuits are printed on a 2-mm thickness optically transparent plexiglas substrate and offer more than 95% transparency. The single rectenna contains a rectangular strip-loop antenna and a SMS7630

Measurements through Rectenna System
International Journal of Measurement Technologies and Instrumentation Engineering, 2013In this paper a rectenna system for wireless transmission of power is presented, describing the correlated tools for the measurement of electromagnetic fields, in order to optimize the system. The first part is dedicated to the benefits of the currently used systems based on rectenna technology as alternative to the traditional supply systems.
