An antenna device disposed on a substrate includes a feed part, a body part, at least one ground plane, and a matching part. The feed part is for feeding electromagnetic signals. The body part for radiating and receiving the electromagnetic signals is electronically connected to the feed part. The body part includes a first radiation part located on a first plane, a second radiation part located on a second plane, and a third radiation part located on a third plane. The second radiation part is electronically connected between the first radiation part and the third radiation part. The ground plane for grounding is disposed on one surface of the substrate. The matching part for impedance matching includes one end electronically connected to one end of the body part and one end of the feed part, and another end electronically connected to the ground plane.
