Abstract

An electronic device is provided. The electronic device includes a front cover forming a front surface, a rear cover forming a rear surface, a sidewall at least partially enclosing a space formed between the front cover and the rear cover and at least partially formed of a conductive member, a display disposed in the space and including a screen region exposed through the front cover, a non-conductive structure disposed in adjacent to the sidewall or in contact with the sidewall in the space and including a first surface facing the front cover and a second surface facing the rear cover, a first antenna pattern overlapping the non-conductive structure and fed with electricity, a second antenna pattern overlapping the non-conductive structure and disposed adjacent to the first antenna pattern to form electromagnetic-field coupling with the first antenna pattern, and an integrated circuit chip feeding electricity to the first antenna pattern

First claim

What is claimed is:

1 . An electronic device comprising:
a front cover forming a front surface of the electronic device; a rear cover forming a rear surface of the electronic device; a sidewall at least partially enclosing a space formed between the front cover and the rear cover and at least partially formed of a conductive member; a display disposed in the space and comprising a screen region exposed through the front cover; a non-conductive structure disposed in adjacent to the sidewall or in contact with the sidewall in the space and comprising a first surface facing the front cover and a second surface facing the rear cover; a first antenna pattern overlapping the non-conductive structure when viewed from top of the non-conductive structure and fed with electricity; a second antenna pattern overlapping the non-conductive structure when viewed from top of the non-conductive structure and disposed in adjacent to the first antenna pattern to form electromagnetic-field coupling with the first antenna pattern; and at least one integrated circuit (IC) chip feeding electricity to the first antenna pattern, wherein the conductive member of the sidewall forms electromagnetic-field coupling with the second antenna pattern, such that the first antenna pattern, the second antenna pattern, and the conductive member form a portion of an antenna device.

2 . The electronic device of claim 1 , further comprising:
a parasitic antenna pattern overlapping the non-conductive structure when viewed from top of the non-conductive structure and disposed in adjacent to the first antenna pattern to form electromagnetic-field coupling with the first antenna pattern.

3 . The electronic device of claim 2 , wherein the first antenna pattern is positioned on a region between the second antenna pattern and the parasitic antenna pattern.

4 . The electronic device of claim 1 , wherein the second antenna pattern is positioned on a region between the first antenna pattern and the conductive member.

5 . The electronic device of claim 1 , further comprising:
a slot formed in the first antenna pattern to receive at least a portion of the second antenna pattern.

6 . The electronic device of claim 5 , further comprising:
a first extension pattern extending from the first antenna pattern and positioned on a portion of a region between the second antenna pattern and the conductive member.

7 . The electronic device of claim 6 , wherein electromagnetic-field coupling is formed between the first extension pattern and the conductive member.
