摘要： More frequency bands are available to use with fewer elements, and, in particular, an antenna gain is increased over a wide frequency range. Two antenna elements 21 and 22 are erected on an antenna base 10. Each of the antenna elements 21 and 22 includes a proximal end portion 21a, 22a, and two arm portions 211a, 211b, 221a, 221b extending in a strip shape in directions away from each other from the proximal end portion 21a, 22b. An inductance of at least one of the two arm portions 221a, 221b of the antenna element 21 is larger than an inductance of a planer conductor having a same material and a substantially same outer shape. An inductance of at least one of the two arm portions 221a, 221b of the antenna element 22 is larger than an inductance of a planer conductor having a same material and a substantially same outer shape.
