PROBLEM TO BE SOLVED: To provide an antenna device which allows for flexible adjustment of each resonance frequency subjected to double resonance.SOLUTION: An antenna device includes a substrate body 2, and a ground surface GND, a first element 3 and a second element 4 formed on the surface of the substrate body. The first element is provided with a feeding point on the substrate side and has first extension E1 through fifth extension E5. The second element has sixth extension E6 through eighth extension E8, and a capacitor loading portion E20, projecting from the way of the fifth extension in the opposite direction from the forth extension, is formed between the sixth extension and eighth extension. |
