Antenna and electronic device comprising the same

An electronic device, comprising:

• a housing forming at least a portion of an exterior of the electronic device;
• a printed circuit board disposed in an inner space of the housing;
• an antenna structure including at least one antenna positioned in the inner space and electrically connected with the printed circuit board, the antenna structure including:
• a conductive plate having an opening, the opening including a first opening and a second opening extending from the first opening toward an edge of the conductive plate;
• a first conductive strip forming a first frequency band and disposed within the first opening and the second opening;
• and
• a second conductive strip forming a second feed for a second frequency band different from the first frequency band;
• and
• a wireless communication circuit electrically connected with the first conductive strip and/or the second conductive strip and configured to transmit and/or receive a radio frequency (RF) signal having a frequency in a range of about 3 GHz to 300 GHz,
• wherein the conductive plate comprises a first ground portion and a second ground portion spaced apart from each other with respect to the second opening and configured to electrically couple to the second conductive strip,
• wherein, when viewed from above the conductive plate, a first area where the second conductive strip overlaps with the first ground portion is greater than a second area where the second conductive strip overlaps with the second ground portion.
