1. An electronic device comprising:
- a main board;
a case frame;
an antenna carrier;
an antenna radiator disposed on the antenna carrier, the antenna radiator configured to operate in at least one frequency band;
a ground stub configured to change a frequency band received by the electronic device by selective coupling of the ground stub with the antenna radiator, the ground stub being electrically coupled to, and spaced apart from, the antenna radiator; and
a switching device configured to electrically connect the ground stub to a ground of the main board,wherein the ground stub is insert-molded into the case frame of the electronic device so as to be exposed to an outer side of the case frame.

Abstract
An electronic device is provided. The electronic device includes an antenna radiator configured to operate in at least one frequency band, a ground stub disposed at a coupling location in proximity to the antenna radiator, and a switching device configured to selectively ground the ground stub and a ground of a main board. Thus, the present disclosure is easily applicable without design constraints in terms of space use when the main board and the antenna radiator are separated, and simplifies the assembly and reduces the cost without a separate sub-board.
