TL;DR: In this paper, a dual-band rectenna for radio frequency (RF) energy harvesting is presented, which utilizes the differential field sampling for each polarization and quadruples the overall output voltage by the rectification process.

TL;DR: In this paper, the authors define a physical bound-based array figure of merit for both single and multiband array antennas, which provides a measure to compare their performance with respect to return loss, bandwidth(s), thickness of the array over the ground plane, and scan range.

TL;DR: The proposed system of the Butler matrix in conjunction with the constructed array can be utilized as a common RF front end in a wideband air interface for a small cell 5G application and beyond as it is capable to simultaneously cover all the commercial bands from 2 to 5 GHz.

TL;DR: In this article, the authors developed a modular radio-frequency (RF) energy harvesting system for smart buildings that can act as a power source for sensing devices, which is composed of two modules: a Wi-Fi rectenna system composed of eight dual-polarized patch antennas and 16 rectifiers to produce eight differential voltage sources connected in series and a cellular rectenna systems composed of 8 linear tapered slot antennas and eight rectifiers.

TL;DR: The scope of this work is to investigate asymmetry in a strongly coupled dipole array and exploit its effect for bandwidth and scanning improvement and pixelate parts of the element and optimize this parts with a genetic algorithm.
