Claim:
1. A loop antenna comprising: a first conductor configured to have electrically conductivity, the first conductor including a first pattern and a second pattern, the first pattern being provided along a first surface and including a first feed point, and the second pattern being electrically coupled to the first pattern at a first end of the first surface and being provided to oppose the first pattern; and a second conductor configured to have electrically conductivity, the second conductor including a third pattern and a fourth pattern, the third pattern being provided on the first surface with a gap generating a capacitance between the first pattern and including a second feed point, the fourth pattern being electrically coupled to the third pattern at a second end opposing the first end on the first surface, the fourth pattern overlapping the second pattern so as to cause capacitive coupling or being connected to the second pattern, wherein at least a part of the first pattern is arranged closer to the second end than at least a part of the third pattern and the first feed point and the second feed point are provided so as to include the at least part of the first pattern in a path of current from the first feed point to the second feed point.
