1. An electronic device comprising:
- a metal bezel comprising an antenna radiator in a shape of a loop that is disposed in at least one area of the electronic device, the antenna radiator comprising two grounded locations of which the electrical lengths from a preset power-supplied location are different from each other;
a substrate (printed circuit board (PCB)) for supplying power to the preset power-supplied location of the antenna radiator; and
an inner housing including a first portion having a first conductive pattern, a second portion having a second conductive pattern different from the first conductive pattern and a third portion having a third conductive pattern different from the first conductive pattern and the second conductive pattern and configured to electrically connect the metal bezel and the substrate through each of the first portion, second portion and the third portion,wherein at least one location of the antenna radiator that differs from the power-supplied location is grounded through the substrate, andwherein an operation frequency band of the antenna radiator is adjusted based on at least one of the first conductive pattern, second conductive pattern and the third conductive pattern.

Abstract
An antenna device implemented to prevent the deterioration in radiation performance due to a metal mechanical part and an electronic device including the same is provided. The electronic device includes a metal member in a shape of a loop that is disposed in at least one area of the electronic device and a substrate (printed circuit board (PCB)) for supplying power to a preset location of the metal member in order to use the metal member as an antenna radiator, wherein at least one location of the metal member that differs from the power-supplied location is grounded through the substrate.
