ABSTRACT:
The radiating conductor in an antenna device comprises first forming elements, second forming elements and third forming elements disposed to be coupled in one direction. The first forming elements are formed in a semi-circular shape, and the third forming elements are formed in a band-like shape and have feed points disposed therein. The first forming elements, the second forming elements and the third forming elements have respective maximum lengths gradually reduced in this order.
