Abstract—The present paper intends to link several disciplines in an attempt to describe the concept of wireless electricity. Wireless transmission is useful in cases where interconnecting wires are inconvenient, unaffordable, expensive, hazardous, unwanted or impossible. A large part of the energy sent out by the generating plant must arrive at the receiver to make the system economical. Some common forms of wireless electricity transmission methods are Direct Induction followed by resonant magnetic induction, electromagnetic radiation in the form of microwaves or lasers. With this technology we can reduce power losses produced through wired lines. Different concepts and application of wireless power transmission are discussed in this paper. Introduction
The definition of Wireless Power Transmission is: efficient transmission of electric power from one place to another through vacuum or an atmosphere without the use of wire or any other substance. Maxwell 's theory of electromagnetism, published in 1865 mentions electromagnetic waves moving at the speed of light, and the conclusion that light itself was just a wave. In 1886 H. Hertz performed an experiment with pulsed wireless energy transfer. . He produced an apparatus that generated and detected microwaves in the UHF region. Tesla also performed experiments in the field of pulsed wireless energy transfer in 1899. Tesla 's Magnifying Transmitter, an early type of Tesla Coil that measured 16 meters in diameter, could able to transmit tens of thousands of watts without wires.
In present electricity generation system we waste more than half of its resources. The transmission of power without wires may be one idle alternative for electricity. Future suitable and largest application of the WPT via microwave is a

    The aim of this report is to research wireless antennas and differences between them. Antennas are included 3 types: omnidirectional, semi-directional, and highly-directional. Any antenna has three fundamental properties: gain, directional and polarization. Omnidirectional Antennas. We can use this antenna in a: point-multipoint link, warehouse, hotspot, trade show, airport. The omnidirectional antennas transmit a signal in all directions, it is known dipole ("non-directional") antenna. The…

    Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio. With radio waves distances can be short, such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants…
