Antenna and electronic device comprising same
An electronic device is provided. The electronic device includes an antenna disposed inside the electronic device, and a case which forms at least a part of the outer appearance of the electronic device and which is integrally formed with the antenna through insert injection, wherein the antenna includes at least one stepped portion protruding in a direction toward the inside of the electronic device to form a step, and at least one surface of the stepped portion includes at least one engagement structure formed to face a direction different from the direction in which the case is open.
1. An electronic device comprising:
an antenna disposed inside the electronic device; and
a case defining at least a portion of an exterior of the electronic device and integrated with the antenna through insert injection molding,
wherein the antenna comprises at least one stepped portion protruding in a direction toward inside of the electronic device to provide a step difference, and
wherein at least one surface of the at least one stepped portion comprises at least one engagement structure disposed to face a direction different from a direction in which the case is open.
2. The electronic device of claim 1 , wherein the at least one engagement structure is disposed on the at least one surface of the at least one stepped portion defining a side surface of a space provided in an inner surface of the antenna by the at least one stepped portion.
3. The electronic device of claim 1 , wherein the at least one engagement structure is provided on the at least one surface of the at least one stepped portion disposed at a position close to a gate of an injection mold for the case.
4. The electronic device of claim 1 , wherein an upper surface of the at least one stepped portion comprises a recess disposed to face the protruding direction of the at least one stepped portion.
5. The electronic device of claim 4 ,
wherein the case comprises an opening open to an outside of the case, and
wherein the opening comprises a conduit that passes through the case and the antenna and is connected to the recess.
6. The electronic device of claim 4 , further comprising:
a microphone disposed inside the electronic device,
wherein the microphone is disposed on the upper surface.
7. The electronic device of claim 6 , further comprising:
a waterproof membrane disposed between the microphone and the recess.
8. The electronic device of claim 6 , further comprising:
a waterproof member,
wherein the waterproof member is disposed along a gap generated between the upper surface and the microphone.
9. The electronic device of claim 1 , wherein the antenna comprises a laser direct structuring (LDS) antenna.
10. The electronic device of claim 1 ,
wherein the antenna is molded through insert injection molding, and
wherein the case is integrated with the antenna by being molded through insert injection molding along an outer surface of the antenna after the antenna is molded.
11. The electronic device of claim 1 , further comprising:
a housing that defines at least a portion of the exterior of the electronic device and is coupled to the case,
wherein the housing comprises a protrusion that is insertable into a user's ear.
12. The electronic device of claim 1 , wherein the engagement structure comprises an undercut structure having a socket shape.
13. The electronic device of claim 12 , wherein the undercut structure is provided in a direction perpendicular to the protruding direction of the at least one stepped portion.
14. The electronic device of claim 1 , wherein the engagement structure comprises a protrusion.
15. The electronic device of claim 1 , wherein the antenna is accommodated inside the case in a state of being surrounded by an inner surface of the case.
16. The electronic device of claim 11 , further comprising an ear tip coupled to the protrusion.
17. The electronic device of claim 11 , further comprising a speaker, and the speaker is disposed in an inner space formed by the housing and the case.
18. An antenna comprising:
at least one stepped portion protruding from an inner surface of the antenna to form a step, and
wherein at least one surface of at least one the stepped portion includes at least one engagement structure,
wherein the at least one surface is integrally formed with a case forming at least a part of an exterior of an electronic device through insert injection molding.
19. The antenna of claim 18 , wherein the at least one engagement structure is disposed on the at least one surface of the at least one stepped portion defining a side surface of a space provided in an inner surface of the antenna by the at least one stepped portion.
20. The electronic device of claim 18 , wherein the at least one engagement structure is provided on the at least one surface of the at least one stepped portion disposed at a position close to a gate of an injection mold for the case.
