2015 IEEE Wireless Power Transfer Conference (WPTC), 2015
This paper presents experimental results on several self-complementary bow-tie antenna arrays populated with rectifier diodes. Results with two different diodes are compared, and the number of diodes, antenna polarization, DC load, DC connection (parallel/series) and incident power density are varied.

A High-Efficiency 35GHz Rectenna with compact structure for rectenna arrays
2018 IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP), 2018A 35GHz rectenna with high efficiency and compact structure is proposed in this paper. A patch antenna fed by the coupling slot is employed to receive power from free space. The structure of designed rectifier is compact and printed on the bottom side of the antenna. The input low-pass or band-pass filter of the rectifier is removed.

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.

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
