Antenna assembly including a feed line having air-strip structure and an antenna device using the same

An antenna assembly comprising:

• a base;
• an antenna group including a plurality of radiating elements disposed on the base along a first direction;
• and
• a feed line configured to feed power to the plurality of radiating elements, the feed line having an air-strip structure,
• wherein the feed line includes:
• a plurality of connection line regions configured such that one end of each of the plurality of connection line regions is connected to each radiating element of the plurality of radiating elements, and
• a main line region bent at a predetermined angle at the other end of each of the plurality of connection line regions and formed along the first direction from a side surface of the antenna group,
• wherein each of the plurality of connection line regions is formed parallel to the base.
