1. An antenna apparatus, comprising:
a ground plane;
a plurality of first patch antenna patterns arranged on a level higher than the ground plane and each configured to transmit and/or receive a first radio frequency signal of a first frequency;
a plurality of second patch antenna patterns arranged on a level higher than the ground plane and each having a size smaller than a size of each of the plurality of first patch antenna patterns,
wherein the plurality of second patch antenna patterns include feed patch antenna patterns configured to transmit and/or receive a second radio frequency signal of a second frequency different from the first frequency, and dummy patch antenna patterns which are not fed any of the first and second radio frequency signals,
wherein the plurality of second patch antennas are substantially the same size,
wherein each of the plurality of first patch antenna patterns are disposed to overlap portions of the plurality of second patch antenna patterns in a plan view when viewed from a top of the antenna apparatus, and
wherein one of the dummy patch antenna patterns is disposed between adjacent two first patch antenna patterns and between adjacent two feed patch antenna patterns in the plan view when viewed from the top of the antenna apparatus.
