Antenna and electronic device comprising same

An electronic device comprising:

• a housing comprising a conductive member and a non-conductive member coupled to the conductive member;
• an antenna structure disposed in the inner space of the housing, comprising a substrate that includes a first substrate surface facing a first direction, a second substrate surface facing a second direction opposite to the first substrate surface, and a substrate side surface surrounding a space between the first substrate surface and the second substrate surface, and at least one antenna element disposed to form a beam pattern in the first direction;
• a first support part disposed to at least partially correspond to the second substrate surface in the inner space of the housing;
• a conductive bracket comprising at least one conductive extension part disposed higher than the second substrate surface in a direction perpendicular to the first direction from the first support;
• and
• a wireless communication circuit configured to transmit and/or receive a radio signal in a frequency band specified through the at least one antenna element, and
• when the housing is viewed from the outside, the antenna structure may be disposed at a position overlapping at least partially with the non-conductive member.
