1. An electronic device comprising:
a housing including:
a front plate,
a rear plate facing in a direction opposite to the front plate,
a lateral member surrounding a space between the front plate and the rear plate, wherein at least a part of the lateral member includes a conductive portion positioned between a first non-conductive portion and a second non-conductive portion which are spaced apart from each other; and
a support member integrally extended from the lateral member toward the space and including a conductive part and a polymer portion formed into one body with the conductive part through insert injection;
a conductive extended portion integrally extended from at least a part of the conductive portion to the space between the front plate and the rear plate;
a printed circuit board disposed in the space between the front plate and the rear plate; and
a wireless communication circuit disposed on the printed circuit board and electrically connected to the conductive portion at a first location of the conductive portion spaced apart from the first non-conductive portion,
wherein the first non-conductive portion and the second non-conductive portion are extended from the polymer portion,
wherein the conductive portion is electrically isolated from the conductive part through the polymer portion, the first non-conductive portion and the second non-conductive portion, and
wherein the conductive extended portion is supported by being insert-injected together with the polymer portion in the space.
2. The electronic device of claim 1 ,
wherein the printed circuit board includes a ground (GND), and
wherein the first location of the conductive portion is electrically connected to the ground.
3. The electronic device of claim 1 ,
wherein the printed circuit board includes a ground (GND), and
wherein the conductive portion is electrically connected to the ground at a second location farther from the first non-conductive portion than the first location.
4. The electronic device of claim 1 , wherein the conductive extended portion is extended into the space between the front plate and the rear plate from an end of the conductive portion in contact with the second non-conductive portion.
5. The electronic device of claim 4 , wherein the conductive extended portion is extended to have a predetermined electrical length and a predetermined interval in parallel with the conductive portion in the space between the front plate and the rear plate.
6. The electronic device of claim 4 , wherein the conductive extended portion is extended from the conductive portion in a direction toward the second non-conductive portion.
7. The electronic device of claim 1 , wherein the conductive extended portion is disposed so as not to be overlapped with the printed circuit board when the front plate is viewed from above.
8. The electronic device of claim 1 , wherein the conductive extended portion is disposed so as to be overlapped, at least in part, with the printed circuit board when the front plate is viewed from above.
9. The electronic device of claim 8 , wherein a region of the printed circuit board overlapped with the conductive extended portion is formed as a non-conductive region.
10. The electronic device of claim 1 , wherein the conductive extended portion is branched in a direction toward the space between the front plate and the rear plate between the first location of the conductive portion and the second non-conductive portion.
11. The electronic device of claim 1 , wherein the wireless communication circuit is configured to transmit and/or receive a signal of at least one frequency band in a range of 850 megahertz (MHz) to 3000 MHz through the conductive portion and the conductive extended portion.
12. The electronic device of claim 1 , further comprising:
a display disposed in the space between the front plate and the rear plate and disposed to be visible from an outside through at least a part of the front plate.
