A dual polarization patch rectenna for high power application

Antennas and Propagation Society International Symposium, 1996

A stratosphere radio relay system is being considered for a future communication system. To develop a radio relay platform, microwave power transmission is a good candidate for the energy supply. The Communications Research Laboratory is engaged in developing a rectenna to extract electric power from a transmitted microwave in order to keep flying the stationary platform.

The rectenna device: From theory to practice (a review)

MRS Energy & Sustainability, 2014

ABSTRACTThis review article provides the state-of-art research and developments of the rectenna device and its two main components – the antenna and the rectifier. Furthermore, the history, efficiency trends, and socioeconomic impact of its research are also featured.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 are explored in the context of power transmission and the ever increasing interest in its potential applications at terahertz frequencies, through the infrared and visible spectra. Recent modeling approaches that have predicted controversially hi...

Study and Design of New Rectenna Structures for Wireless Power Transmission Applications

Advances in Computer and Electrical Engineering, 2020

This chapter presents many research works that have been carried out to deal with the problem of power supply to remote sensors. A 2.45 GHz voltage multiplier rectifier was validated to deliver 18V of output voltage with a conversion efficiency of 69%. Another rectenna was fabricated at 5.8 GHz of the Industrial Scientific Medical band and reach a measured voltage of 7.4V at 18 dBm. The third structure is about a series rectifier working at 2.45 GHz associated with a microstrip low pass filter which produces a supplying voltage of 11.23V. Added to the aforementioned results, the objective in this work is to design, optimize and realize two structures: A dual band patch antenna working at 2.45 GHz and 5.8 GHz, and a compact rectifier circuit at 2.45 GHz for the power supply of low-consumption devices. This rectifier has been designed using Advanced Design System. The bridge topology was employed on an FR4 substrate. A good matching input impedance was observed and high conversion eff...

A Wideband and Compact Circularly-Polarized Rectenna for Low Power Application

2017

This paper presents a wideband and compact circularly polarized rectenna composed by an Archimedean spiral antenna that covers the S and C frequency bands and a silicon Schottky diode. This rectenna (rectifier + antenna) is used for electromagnetic energy harvesting over a wide frequency band, in order to power autonomous wireless sensors used for satellite health monitoring. For low incident power densities (around 14 µW/cm²) the measured efficiency of at least 19% between 2GHz and 3.5GHz can be achieved using this rectenna. The efficiency may reach 37% at some frequencies in this wideband operating bandwidth.

Review of Modern Solar Power Satellite and Space Rectenna Systems

2020

This paper presents the review and analysis of modern space solar power satellite system and space rectenna. There is a challenge to collect and transmit large amount of energy from space to earth using microwave power transmission technology without the interference with communication satellites such as military operations systems and aircraft radar systems. This study focuses on Low Earth Orbit (LEO) location of the space satellite for maximum efficiency. Microwaves of 5.8 GHz frequency with efficiency of 85% will be used to transmit the electric power from the space satellite to the rectenna. Space-based solar power system is different from the current solar power collection methods. The space solar power method uses a satellite placed on an orbit to collect the solar energy instead of on earth's surface. Research found space-based solar power to be uneconomical but new developments have paved ways for space solar power exploitation. The space-based section of the system cons...
