摘要： An antenna apparatus includes: a first dipole antenna pattern; a feed line electrically connected to the first dipole antenna pattern; and a first ground plane disposed rearward of the first dipole antenna pattern and spaced apart from the first dipole antenna pattern; wherein the first ground plane forms a step-type cavity, and width of a rear portion of the step-type cavity is different from a width of a front portion of the step-type cavity.
