Abstract (in Japanese) (See Japanese page) 
(in English) We have studied the helmet antenna. However, it has a problem that the gain decreases in proximity to human head. In this study, we improve the gain reduction by using the inverted-F antenna on the hemispherical ground plane in proximity to human head. As a result, we could confirm that the gain was obtained of -2.6 dBi in proximity to human head by changing the antenna forms and antenna height.
