Abstract (in Japanese) (See Japanese page) 
(in English) It has been reported that the planar dipole antenna has two resonance mode, and the input impedance is transformed 300 Ω to 50 Ω by adding a quarter wavelength feed line. Moreover, adjusting the spacing and width of the feed line improves the broadband characteristic. However, the feed line is too big to be mounted on a small terminal. In this report, in order to mount the folded dipole antenna with feed line to a small terminal for WiMAX, we investigate a miniaturization of the feed line and behavior of the antenna on the small ground plane (50 mm×80 mm). The folded dipole antenna on the ground plane has two resonance mode. Moreover, the impedance characteristic can be modified by adjusting the width of antenna and feed line without changing the length of the feed line. A proposed antenna has wideband characteristic which covers the bandwidth of 2.5 GHz band and 3.5 GHz band for WiMAX with a feed line of approximately one eleventh wavelength.
