Thus, the spae-saving antenna system is realized, which copes with broadbanding (a plurality of bands), attains an excellent gain and maintain the non-directivity of the vertically polarized wave in each band. Since the base body 110 and the conductor antenna 120 are fixed in a parted state to each other, the base body 110 and the conductor antenna 120 are surely fixed. COPYRIGHT: (C)2008,JPO&INPIT
