Abstract

An electronic device is provided. The electronic device includes a housing comprising a conductive part, and a first nonconductive part connected to the conductive part, an antenna structure positioned inside the housing, and a pen input device attachable/detachable to/from the housing, wherein the pen input device comprises a second nonconductive part having at least a portion thereof overlapping the first nonconductive part when viewed in a direction in which a main beam of the antenna structure is radiated while the pen input device is attached to the housing, and at least a portion of the at least one antenna element overlaps the first nonconductive part and the second nonconductive part.

First claim

What is claimed is:

1. An electronic device comprising:
a housing comprising a conductive portion and a first non-conductive portion connected to the conductive portion;
an antenna structure located inside the housing, the antenna structure comprising:
a printed circuit board comprising a first surface and a second surface facing away from the first surface, and
at least one antenna element located on the first surface or inside the printed circuit board to be closer to the first surface than the second surface; and

a pen input device detachable from the housing,
wherein the pen input device comprises a second non-conductive portion at least partially overlapping the first non-conductive portion when viewed in a direction in which a main beam of the antenna structure is radiated while the pen input device is attached to the housing, and
wherein at least a portion of the at least one antenna element overlaps the first non-conductive portion and the second non-conductive portion.

2. The electronic device of claim 1 ,
wherein the pen input device comprises a tubular housing formed of a non-conductive material, and
wherein the second non-conductive portion comprises:
a partial section of the pen input device that overlaps the first non-conductive portion and is included in the tubular housing or overlaps the first non-conductive portion and is connected to the tubular housing when viewed in the direction in which the main beam is radiated while the pen input device is attached to the housing, and
a non-conductive member located in an inner space of the partial section.

3. The electronic device of claim 2 , wherein the non-conductive member comprises a dielectric lens.

4. The electronic device of claim 2 ,
wherein the pen input device comprises two magnetic bodies located inside the pen input device, and
wherein the second non-conductive portion is located between the two magnetic bodies when viewed in the direction in which the main beam is radiated while the pen input device is attached to the housing.

5. The electronic device of claim 2 ,
wherein the pen input device comprises an assembly accommodated in the tubular housing,
wherein the assembly comprises:
a pen tip sensor comprising a pen tip and configured to generate a position signal and a pen pressure signal of the pen input device,
a battery, and
a printed circuit board disposed between the pen tip sensor and the battery and electrically connected to the pen tip sensor and the battery, and

wherein the second non-conductive portion is spaced apart from the assembly with the battery interposed therebetween.

6. The electronic device of claim 5 , wherein the pen tip sensor is configured in an electro-magnetic resonance (EMR) type, an active electrical stylus (AES) type, or an electric coupled resonance (ECR) type.

7. The electronic device of claim 1 ,
wherein the housing comprises:
a front plate,
a rear plate disposed on an opposite side to the front plate, and
a lateral member that at least partially surrounds a space between the front plate and the rear plate, and

wherein the electronic device further comprises a display located in the space and visually exposed through the front plate.

8. The electronic device of claim 7 , wherein the pen input device is configured to be detachably attached to the rear plate.

9. The electronic device of claim 7 , wherein the pen input device is configured to be detachably attached to the front plate not to overlap the display when viewed from above the front plate.

10. The electronic device of claim 7 , wherein the pen input device is configured to be detachably attached to the lateral member.

11. The electronic device of claim 1 , further comprising:
a radio communication circuit disposed on the second surface,
wherein the radio communication circuit is electrically connected to the at least one antenna element and is configured to transmit and/or receive a signal in a selected or predetermined frequency band.

12. The electronic device of claim 11 , wherein the radio communication circuit is configured to transmit and/or receive a signal of at least a partial frequency band from 3 GHz to 100 GHz via the at least one antenna element.

13. The electronic device of claim 1 ,
wherein the at least one antenna element comprises a first antenna element and a second antenna element, and
wherein the first antenna element and the second antenna element constitutes an antenna array.

14. The electronic device of claim 1 ,
wherein the pen input device further comprises at least one conductive portion coupled to the second non-conductive portion and located inside the pen input device; and
wherein the at least one conductive portion overlaps the at least one antenna element when viewed in the direction in which the main beam is radiated while the pen input device is attached to the housing.

15. The electronic device of claim 14 , wherein the pen input device further comprises a rotation device located inside the pen input device and connected to the at least one conductive portion to move a position of the at least one conductive portion.

16. The electronic device of claim 1 , wherein the antenna structure is spaced apart from the first non-conductive portion so as to form an air gap therebetween.

17. The electronic device of claim 1 , wherein the second non-conductive portion is formed in one of a bar or a cross shape.

18. The electronic device of claim 2 , wherein the pen input device further comprises a plurality of conductive members arranged within the tubular housing and corresponding to a number of antenna elements.
