“…Although Nahas 7 first developed a model (using a distributed transmission-line technique including skin-effect losses) to simulate the top performance of a rectenna utilising a dipole antenna and a conventional SBD, his prediction of an 80% upper boundary (most of the losses came from the diode rectifier) was later improved when Brown 82 experimentally demonstrated what is to date, the highest ever recorded efficiency at the 2.45 GHz band of 92%. This was made possible by using the then well established Pt/GaAs Schottky diode and supported Brown's predictions that 100% efficiency is possible for this device 44,82 . In another attempt to model the efficiency, Gutman & Borrego 51 predicted an upper boundary of 85% incorporating numerous rectifier outputs interconnected to a common DC load.…”

The Rectenna (RECTifying antENNA), which was first demonstrated by William C. Brown in 1964 as a receiver for microwave power transmission, is now increasingly researched as a means of harvesting solar radiation. Tapping into the growing photovoltaic market, the attraction of the rectenna concept is the potential for devices that, in theory, are not limited in efficiency by the Shockley-Queisser limit. In this review, the history and operation of this 40-year old device concept is explored in the context of power transmission and the ever increasing interest in its potential applications at THz frequencies, through the infra-red and visible spectra. Recent modelling approaches that have predicted controversially high efficiency values at these frequencies are critically examined. It is proposed that to unlock any of the promised potential in the solar rectenna concept, there is a need for each constituent part to be improved beyond the current best performance, with the existing nanometer scale antennas, the rectification and the impedance matching solutions all falling short of the necessary efficiencies at THz frequencies. Advances in the fabrication, characterisation and understanding of the antenna and the rectifier are reviewed, and common solar rectenna design approaches are summarised. Finally, the socio-economic impact of success in this field is discussed and future work is proposed.

“…The transmission efficiency in this experiment was not satisfying, despite the impractically high dimensions of the transmitter and receiver rectenna. Developing rectennas to achieve the best efficiency, researchers made efficiency improvements during 1992-1994, concentrating on 2.45 and 35 GHz [9][10][11][12]. In 2000, at the Jet Propulsion Laboratory (JPL), based on the availability of the high power X-band sources an experiment of 8.51 GHz was held [13].…”

Keeping the power hungry, smart wireless communication devices up and running became a challenging issue due to the need for continuous supply of battery power required for fulfilling all the functions. Since the battery capacity is limited, it needs to be recharged as often as possible. Hence, rather than spreading wires all around, it is a promising solution to cover the medium with electricity wirelessly or create charging points around residential premises based on Wireless Power Transmission technology. The work presented here involves investigation of the possibility of providing wireless charging points within a room and analyzing the choice of best frequency and best pulse shape for transmitting power wirelessly within a distance smaller than 10 m in order to charge batteries of such devices as smart phones. The parameters that can be adjusted to maximize efficiency of wireless power transmission and the relationship between the choice of frequency, pulse shape and distance is investigated. Antenna design will be left as a subject for future study.
