Novel Beam Forming Antenna Technology for 2nd Step WPT System

In 2022, ITU-R (International Telecommunication Union - Radicommunication Sector) published a recommendation document of wide beam WPT. In the same year, new radio regulation of the wide beam WPT was established in Japan. Recently there are over 800 permitted WPT based stations in Japanese buildings and a lot of battery-less IoT sensors are active only by the wireless power. This is a great step for the WPT technology, however, it's tiny step only with over 800 WPT base stations in Japan. For the next step of the WPT, we need a novel beam forming antenna technology to increase the beam efficiency, to supress the unexpected interference to the victims and to keep safety. In this talk, novel beam forming antenna technology and novel beam forming algorism suitable for the WPT are introduced. Expectation for 2nd step WPT business also is introduced.
