Electronic device comprising antenna

An electronic device comprising:

• a housing including a first plate, a second plate facing in a direction opposite to the first plate, and a side member surrounding a space between the first plate and the second plate and including a first edge;
• a window disposed in at least a portion of the first plate;
• a display panel, at least a portion of which is viewable through the window;
• a PCB disposed between the display panel and the second plate;
• a rear structure disposed between the PCB and the second plate, coupled to or integrated with the side member, and including a first area and a second area that are adjacent to the first edge;
• an antenna structure disposed on the rear structure,
• wherein the antenna structure includes:
• a conductive pattern including a first point, a second point, and a third point,
• wherein the conductive pattern includes:
• a first conductive pattern having a first length and extending from the first point in a first direction, and including the second point, wherein the first point and second point are electrically connected;
• a second conductive pattern having a second length that is smaller than the first length and extending from the first point in a second direction that is opposite to the first direction, and including the third point electrically connected to a ground of the PCB;
• and
• a third conductive pattern extending from the first point to have a third length that is shorter than the first length;
• and
• a wireless communication circuit electrically connected to the first point, and configured to transmit and/or receive a first signal of a first frequency range and a second signal of a second frequency range that is higher than the first frequency range,
• wherein a first distal end of the first conductive pattern, a second distal end of the second conductive pattern, and a third distal end of the third conductive pattern are located to be spaced apart from the first edge,
• wherein the first conductive pattern includes a first part spaced apart from the first edge by a first interval, and a second part spaced apart from the first edge by a second interval that is smaller than the first interval, and
• wherein the third conductive pattern is disposed in the first area between the first edge and the first part of the first conductive pattern.
