Wireless Power Transmission and Reception Using Rectenna


Kuchipudi Durga Prasad , Mizan Tepi University; Dr. Kuntigorla Saidulu




The search for “inexhaustible” energy resources to satisfy long term needs is a high priority. Solar Power Satellites answer mankind’s energy needs in the 21st century. Can, infact 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. The solution is wireless power transmission from space through a system consisting of Solar Power Satellite and RECTENNA (RECtifying anTENNA) by Microwaves. The principal advantage of the space location is its independence of weather and day-night cycle and is pollution free. 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. Space solar power stations are costly because of the great size of their radiating and receiving antennas. It is shown that a correct choice of the field distribution on the radiation antenna allows us to increase the wireless power transmission efficiency and to lessen its cost. Antenna and Rectenna sizes are chosen such that the rectenna is situated in the antenna’s Fresnel’s area (but not in the far area as in the ordinary radio communication). This paper thoroughly describes the construction of spacetenna and rectenna to increase the effectiveness of WPT. Compared to today's energy sources, the SPS and rectenna system is an economically competitive large scale energy source, and in fact appears to offer a much less expensive energy source once significant space-based infrastructure is established. In addition, the SPS and rectenna system has strong advantages in terms of environmental issues.
