1. An antenna apparatus, comprising:
a ground substrate;
a feeding point provided on the ground substrate;
a first loop antenna of which one end is electrically connected to the feeding point and of which another end is electrically connected to the ground substrate and moreover which operates at a first frequency; and
a second loop antenna of which both ends are respectively connected to a first end point and a second end point of the first loop antenna and which operates at a second frequency, wherein
a space between the first end point and the second end point forms a gap with a range in which the first loop antenna is capable of resonating at the first frequency.
