PROBLEM TO BE SOLVED: To provide an antenna which may be used in a wide band.SOLUTION: An antenna 10A includes: a dielectric substrate 11; an unbalanced feeding material 12 having a non feeding part 23 and a feeding part 24; a resonance conductor 13 having a connection area 26, a first resonance area 27, and a second resonance area 28; a ground conductor 14 including a first ground area 32 and a second ground area 33; and a radiation conductor 15 including a first radiation area 37 and a second radiation area 38. In the antenna 10A, first to third radiation step portions 42a to 42c are formed at a first rear end part 41 of the second radiation area 38 and first to third radiation step portions 44a to 44c are formed at a second rear end part 43 of the second radiation area 38. |
