Solar Power Satellites SPS converts solar energy in to micro waves and sends that microwaves in to a beam to a receiving antenna on the Earth for conversion to ordinary Electricity. The SPS concept, first proposed in in the United States, has recently started attracting increased public attention as a promising energy system that can be used to resolve global environmental and energy problems. SPS is a clean, large-scale, stable electric power source. MPT contains microwave beam, which can be directed to any desired location on Earth surface.
Efficiency is quantified by the ratio of DC output power after conversion to the received frequency power of the antenna as shown below in Equation Microwave power transmission. Rectenna Total Efficiency Equation [ Ojha13 ].
In sum, the rectenna at the target captures microwave radiation from the generator through the antenna, the microwaves pass through filters and diodes, and then to the rectifying circuit which transfers DC power to the target system [ Choudhary11 ].
Systems attempting to wield MPT to transfer power wirelessly can thus use the described configuration. Importantly, the system is quite scalable. Large microwave generators can be constructed to transmit a greater amount of microwaves over space, and, as shown in Figure 3 below, rectenna units can be arranged in an array to capture as much of the transmitted microwave radiation as possible to be converted to DC.
Front and back picture of array of rectenna [ Huang13 ] MPT has several exciting applications, both for existing technologies and for theoretical systems still being researched. Applications of WPT Several applications of wireless power transfer are apparent and obvious.
Firstly, WPT could eliminate traditional charging systems in place today.
Instead of plugging in a mobile phone or laptop via power cord to charge the battery, wireless power can be harnessed and implemented in a home such that a laptop and phone charge continuously and wirelessly without the need for plugging anything in.
Higher level applications include charging of electric vehicles EVs. As EVs become more and more prevalent on the roads, the feasibility of driving such a vehicle can be maximized via stationary, and even mobile, WPT systems.
Future and theoretical applications include a potential solution to renewable energy for the planet, by means of satellites collecting sunlight and sending power back to earth through MPT.
Applications of WPT are described in this section. What these devices all have in common is the need to recharge their internal battery so that the device can be used while mobile.
Such is the paradox of portable devices: WPT has the potential to disrupt and revolutionize the traditional portable device, not only by making mobile devices more convenient by eliminating the need for a physical power supply, but also safer power cords carry risk of shock and can cause firesas well as a reduced cost for consumers [ Kesler13 ].
Research has even been done into multi-hop WPT systems, wherein a generator transmits power wirelessly to targets, which can then in turn become sources for other targets, and transfer power wirelessly to those targets.
Thus, a network of WPT can be created to support several devices [ Rault13 ]. One of the drawbacks of electric vehicles is their battery. Electric vehicles currently need to be plugged in to recharge their internal batteries, and take many hours to do so [ Shwartz12 ]. However, many envision that in the near future, one need only park her car in a pre-determined spot in her driveway and the car will charge wirelessly and automatically [ Kesler13 ].
Thus a great deal of research has been done into WPT, specifically through the MPT mechanism, and how it can be used for the charging of electric vehicles.RS Microwave Company, Inc., founded in , is an internationally respected leader in RF and microwave filter technology and initiativeblog.comd in Butler, NJ approximately 25 miles from New York City, we are AS Certified and specialize in the design and production of quality custom filters and multiplexers to aerospace and deep space applications using state-of-the-art CAD techniques.

Abstract: Microwave power transmission (MPT) is the wireless transfer of large amounts of power at microwave frequencies from one location to another.
MPT research has been driven primarily by the desire to remotely power unmanned aerial vehicles (UAVs) and by the concept of space solar power (SSP. Microwave Power Transmission Technologies for Solar Power Satellites Abstract: A solar power satellite (SPS) is a renewable energy system that converts the sun's energy into electricity in space and transmits it to Earth using microwaves.
Thin sapphire windows using resonant tube cooling can transmit 1 megawatt of microwave power across an air/vacuum interface.
Microwave transmission is the transmission of information or energy by microwave radio waves. Although an experimental mile (64 km) microwave telecommunication link across the English Channel was demonstrated in
