Satellite solar wireless power transfer for baseload ground supply: clean energy for the future
Wireless power transfer WPT , wireless power transmission , wireless energy transmission WET , or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, a transmitter device, driven by electric power from a power source , generates a time-varying electromagnetic field , which transmits power across space to a receiver device, which extracts power from the field and supplies it to an electrical load. The technology of wireless power transmission can eliminate the use of the wires and batteries, thus increasing the mobility, convenience, and safety of an electronic device for all users. Wireless power techniques mainly fall into two categories, near field and far-field. In near field or non-radiative techniques, power is transferred over short distances by magnetic fields using inductive coupling between coils of wire , or by electric fields using capacitive coupling between metal electrodes. In far-field or radiative techniques, also called power beaming , power is transferred by beams of electromagnetic radiation , like microwaves  or laser beams.
Handbook of Antenna Technologies pp Cite as. The transmitting and receiving antenna designs for the microwave wireless power transmission MPT systems are illustrated in this chapter. After introducing a brief history, this chapter describes the components of a MPT system and the operation band selections. Several rectennas and arrays with different structures and performances are designed after analyzing the special considerations of the receiving antennas. To obtain the maximum DC-DC direct current to direct current system efficiency, the aperture level distributions of the transmitting antenna are investigated with consideration of the receiving rectennas. A MPT system design operating at C-band is explained based on the above discussion and the summary is made finally.
Show all documents Wireless power transfer WPT has been made feasible in recent years due to advances in technology and better implementations of transfer techniques, such as Microwave Power Transfer MPT. In order to reduce the transmission and distribution losses. The MPT system works by converting microwave into power by using special devices called as rectenna The applications of MPT are numerous, not only to change the way existing technologies work, but also as theoretical constructs for future constructs. While the benefits are great, there are many limitations and drawbacks of MPT. The advantages, disadvantages, biological impacts and applications of WPT are also presented.
Antennas in Microwave Wireless Power Transmission
With the rapid development of the wireless systems and demands of low-power integrated electronic circuits, various research trends have tended to study the feasibility of powering these circuits by harvesting free energy from ambient electromagnetic space or by using dedicated RF source. Wireless power transmission WPT technology was first pursued by Tesla over a century ago. However, it faced several challenges for deployment in real applications. Recently, energy harvesting and WPT technologies have received much attention as a clean and renewable power source. Rectenna rectifying antenna system can be used for remotely charging batteries in several sensor networks at internet of things IoT applications as commonly used in smart buildings, implanted medical devices and automotive applications.
Space-based solar power SBSP is the concept of collecting solar power in outer space and distributing it to Earth. Potential advantages of collecting solar energy in space include a higher collection rate and a longer collection period due to the lack of a diffusing atmosphere , and the possibility of placing a solar collector in an orbiting location where there is no night. Space-based solar power systems convert sunlight to microwaves outside the atmosphere, avoiding these losses and the downtime due to the Earth's rotation , but at great cost due to the expense of launching material into orbit. SBSP is considered a form of sustainable or green energy , renewable energy , and is occasionally considered among climate engineering proposals. It is attractive to those seeking large-scale solutions to anthropogenic climate change or fossil fuel depletion such as peak oil. Various SBSP proposals have been researched since the early s,   but none are economically viable with present-day space launch infrastructure. Some technologists speculate that this may change in the distant future if an off-world industrial base were to be developed that could manufacture solar power satellites out of asteroids or lunar material, or if radical new space launch technologies other than rocketry should become available in the future.

Rectenna Systems for RF Energy Harvesting and Wireless Power Transfer
We can, in fact directly convert solar energy into electrical energy with the use of solar cells, but sunlight diffuses at night time from the earth. If the need arises for 24 hours power supply, we are helpless. Modern techniques enables us to create a platform in space carrying solar batteries, generators converting electric current worked out by them into the Electromagnetic field energy of ten centimeter range microwaves and antenna forming electromagnetic wave beam. On the earth, the other antenna rectenna receives the beam and it is converted into electric current again. The principal advantage of the space location is its independence of weather and day-night cycle and is pollution free. Antenna and Rectenna sizes are chosen such that the rectenna is situated in the antennas Fresnels area.

Based on the need for clean, non-polluting sources of energy, and a trend to abandon nuclear power generation, the solar power source appears to be an attractive alternative energy source. Instead, the concept of solar power satellite SPS systems has been presented so as to solve this problem. One of the key technologies for the SPS system is the wireless power transmission system, which includes DC to RF converters in the transmitters, the retrodirective beam control system and the receiving rectenna system. In this work, the overall transmitting system has been analyzed in a system perspective. The techniques for generating and transmitting a high intensity microwave beam for solar power transmission can be divided into the centralized and the distributed approaches.
Metrics details. Many factors are influencing the acceptability of energy technology. The transformation of the energy sector is looking for clean energy technology that is also suitable for baseload power generation. Terrestrial solar energy has many obstructions, so solar power from space without any hindrance has higher priority for adoption, and it is suitable for future energy continuous demand supply. As technology is advancing, the possibility of satellite solar-based power station is more than a science fiction now and is possible in the coming future.
