Abstract(in Japanese) (See Japanese page)
Abstract(in English) It is well known that a standing wave having a central portion as an antinode and both ends as nodes is formed on a half-wavelength dipole antenna in case of central feeding. It is also well known that the current flowing through the antenna has phase lag with respect to the supply voltage or the voltage at the feeding point of the antenna. However, it is not known well the fact that the current of each part of the antenna contains lagging component of about 7% with respect to the current of the feed point. And the lagging current plays an important role in potential distribution and energy radiation of the antenna. On this time, simulation analyses were conducted with VSTL of surge analysis software developed by CRIEPI. As a result, the above-mentioned matters and energy transportation are clarified.
