<P>PROBLEM TO BE SOLVED: To provide an antenna device capable of covering a wider frequency band by effectively separating coupling between antenna elements. <P>SOLUTION: There is provided an antenna device comprising: a first and second feed elements which are connected to the periphery of a ground conductor and have an inverse F shape; and a coupling element which are formed so as to be isolated from the ground conductor, and arranged so as to have one end electrostatically coupled to the first feed element and the other end electrostatically coupled to the second feed element. The coupling element is constituted by a first pad part formed in the vicinity of the one end, a second pad part formed in the vicinity of the other end, and a linear part which has a linear shape having width narrower than those of the first and second pad parts and electrically connects the first and second pad parts. <P>COPYRIGHT: (C)2013,JPO&INPIT |
