PROBLEM TO BE SOLVED: To provide an antenna device having a band characteristic of wide bandwidth, capable of facilitating adjustment of the resonance frequency and bandwidth of a primary mode.SOLUTION: In an antenna device 1, a first linear antenna element 3 connected to a ground pattern 2 and a second linear antenna element 5 connected to a feeding point 4 are capacity-coupled with each other at a capacity coupling section 7 of a front end. At the middle of each of the first linear antenna element 3 and a second linear antenna element 5, inductive elements L1, L2 are interposed. |
