The research of wireless transmission technology in Japan can be used for future space generation Phoenix Technology News Beijing on October 7th news, according to foreign media reports, the Japanese researchers in the development of long distance transmission of large amounts of electric power wireless transmission system. A variety of prototype products and projects have a common goal: from sky to ground transmission. The ultimate goal of the research is to create a huge solar array in the sky that is free from the effects of the earth’s weather, and to transmit electricity to the ground receiving device. Compared to this goal, there is still a considerable gap between the current prototype products, but its transmission capacity is still far beyond the current smart phones and other devices wireless charging products. At this week’s Ceatec show, J SpaceSystems shows an antenna for receiving high energy microwave signals. Known as "rectenna" J SpaceSystems antenna belongs to the flat panel antenna, the signal frequency is 5.8GHz. J SpaceSystems was successfully carried out at a distance of about 50 m on the transmission test, although the energy loss is considerable. It is a 1.2X 1.2 m antenna input power of 1.8 kilowatts, from a X of 2.3 m antenna to obtain a power of 340 watts. MITSUBISHI heavy industry is also conducting a similar study, last year, 500 meters from the success of the transmission test of 10 kilowatts, a record of similar research projects in Japan at the time of the new record. MITSUBISHI heavy industries in the use of the giant launch and receive antenna. With the continuous development of wireless transmission technology, it will have several uses. The utility model has the advantages that the utility model can be used for short distance transmission in a factory, and the utility model is convenient for reconfiguring the machine, the sensor and the workstation without rewiring. Another potential use is the use of balloons to power outages caused by natural disasters in the region. In addition, this technology can also provide for the UAV flying in the air and other similar objects. However, compared to design and build giant solar array in the sky, to the ground transmission, the use of only. To achieve this goal, there is much work to be done, including reducing transmission losses. Japan’s space agency admitted that the use of solar cells in space power generation is not a new idea. Similar projects in other countries have been shut down for lack of government support. Japan’s space agency will continue to carry out research work, but at the same time aware of the difficulty of studying related technologies, to overcome the difficulties in the establishment of space solar power plants, it takes time and effort".
