Electronic device with antenna device
An electronic device with an antenna device is provided. The electronic device includes a case member that includes a first face, a second face disposed opposite to the first face, and side walls that enclose a space between the first face and the second face, a first metallic member that forms at least a portion of the side walls of the case member or is formed adjacent to the side walls, a metal pattern disposed within the case member and extends from a portion of the first metallic member to another portion of the first metallic member, the first metallic member and the metal pattern electrically forming at least a portion of a closed loop, a wireless communication circuit electrically connected to a portion of the metal pattern, a ground member positioned within the case member, and a portion of the metal pattern disposed adjacent to the ground member.
1. An electronic device having an antenna device, the electronic device comprising:
a case member comprising a first face, a second face disposed opposite to the first face, and side walls that enclose a space between the first face and the second face;
a first metallic member that forms at least a portion of the side walls of the case member or is formed adjacent to the side walls;
a metal pattern disposed within the case member that extends from a portion of the first metallic member to another portion of the first metallic member, wherein the first metallic member and the metal pattern electrically form at least a portion of a closed loop;
a wireless communication circuit electrically connected to a portion of the metal pattern; and
a ground member disposed within the case member, wherein at least a portion of the metal pattern is disposed adjacent to the ground member.
2. The electronic device of claim 1 , wherein when the wireless communication integrated circuit operates, an electromagnetic coupling is formed between at least a portion of the metal pattern and the ground member.
3. The electronic device of claim 1 , further comprising a second metallic member disposed adjacent to an end of the first metallic member, the second metallic member forming another portion of the side walls of the case member.
4. The electronic device of claim 3 , wherein a first end of the second metallic member is fed with power and a second end of the second metallic member is connected to the ground member to form a loop antenna.
5. The electronic device of claim 4 , wherein one of the first or second ends of the second metallic member is disposed adjacent to an end of the first metallic member.
6. The electronic device of claim 3 , wherein the second metallic member is fed with power between opposite ends thereof and the opposite ends are connected to the ground member to form a slot antenna.
7. The electronic device of claim 6 , wherein one of the ends of the second metallic member is disposed adjacent to an end of the first metallic member and the metal pattern.
8. The electronic device of claim 3 , wherein the second metallic member forms a loop antenna or a slot antenna, and wherein the electronic device further comprises a third metallic member disposed inside the loop antenna or the slot antenna formed by the second metallic member.
9. The electronic device of claim 8 , wherein the third metallic member forms an inverted f antenna (IFA).
10. The electronic device of claim 1 , further comprising:
a support member disposed inside the case member; and
a circuit board installed on the support member and disposed to face at least a portion of the metal pattern,
wherein the metal pattern is disposed adjacent to at least one of the support member and the circuit board.
11. The electronic device of claim 10 , wherein the ground member is provided on at least one of the support member and the circuit board.
12. The electronic device of claim 1 , wherein a portion of the first metallic member and the metal pattern forms a shape of any one of a polygonal shape, a partially circular shape, and an oval shape.
13. The electronic device of claim 1 , wherein the metal pattern is disposed closer to one end of the first metallic member than to the other end of the first metallic member.
14. The electronic device of claim 1 , wherein the first metallic member is fed with power through the metal pattern to form an antenna with a first resonant frequency and a second resonant frequency, and
wherein a second frequency band associated with the second resonant frequency is higher than a first frequency band associated with the first resonant frequency.
15. The electronic device of claim 1 , further comprising:
second metallic members disposed adjacent to opposite ends of the first metallic member, respectively, the second metallic members forming another portion of the side walls of the case member,
wherein one of the second metallic members positioned at one side of the case member is connected to power at one end that is adjacent to the first metallic member, and is connected to the ground member at the other end, and
another of the second metallic members positioned at the other side of the case member is connected to the ground member at the opposite ends thereof and is fed with power at a point between the opposite ends.
