Abstract
According to the ultrawideband communication antenna, since surfaces of the antenna element are coated with the first resin layer and the second resin layer each of which is mixed with the nonmagnetic metal powder and has an insulating property and a high specific inductive capacity, the size is largely reduced. Further, since the nonmagnetic metal powder is used, the first resin layer and the second resin layer are free from a loss of magnetism generated therein, thereby enabling to maintain a loss of the antenna to a low level.
