Antenna apparatus

An antenna apparatus comprising:

• a dielectric layer;
• a first patch antenna pattern disposed on an upper surface of the dielectric layer;
• a first feed via penetrating the dielectric layer by at least a portion of a thickness of the dielectric layer and spaced apart from the first patch antenna pattern;
• and
• a coiled feed pattern electrically connected to an upper end of the first feed via, spaced apart from the first patch antenna pattern, and configured to provide a feed path to the first patch antenna pattern, wherein at least a portion of the coiled feed pattern is coiled,
• wherein a portion of the coiled feed pattern extends in different directions from one end of a coiled portion of the coiled feed pattern.

• an extended patch antenna pattern at least partially overlapping the coiled feed pattern in a vertical direction;
• and
• a second patch antenna pattern disposed on the first patch antenna pattern and at least partially overlapping the first patch antenna pattern in the vertical direction.
