Abstract

An electronic apparatus is provided. The electronic apparatus includes at least one first antenna radiator, a main board including a feed part that is spaced apart from at least one portion of the at least one first antenna radiator to overlap the at least one portion of the at least one first antenna radiator and feeds an electric current to the at least one first antenna radiator according to an indirect feed method, at least one second antenna radiator disposed on a housing of the electronic apparatus, at least one first connection member for electrically connecting the at least one first antenna radiator to the at least one second antenna radiator, and at least one second connection member for electrically connecting a ground part formed on the main board to the at least one second antenna radiator. Also, other various exemplary may be implemented.

First claim

What is claimed is:

1. An electronic apparatus comprising:
at least one first antenna radiator;
a main board including a feed part that is spaced apart from at least one portion of the at least one first antenna radiator to overlap the at least one portion of the at least one first antenna radiator and feeds an electric current to the at least one first antenna radiator according to an indirect feed method;
at least one second antenna radiator disposed on a housing of the electronic apparatus;
at least one first connection member for electrically connecting the at least one first antenna radiator to the at least one second antenna radiator; and
at least one second connection member for electrically connecting a ground part of the main board to the at least one second antenna radiator.

2. The electronic apparatus of claim 1 , further comprising at least one third antenna radiator which has at least one portion spaced apart from the feed part to overlap the feed part and receives an electric current from the feed part according to an indirect feed method and is electrically connected to the ground part of the main board,
wherein the feed part is disposed between the at least one first antenna radiator and the at least one third antenna radiator.

3. The electronic apparatus of claim 2 , wherein a frequency band of a signal transmitted and received by a resonance of the at least one first antenna radiator and the at least one second antenna radiator is different from that of a signal transmitted and received by a resonance of the at least one third antenna radiator.

4. The electronic apparatus of claim 2 , wherein a frequency band of a signal transmitted and received by a resonance of the at least one first antenna radiator and the at least one second antenna radiator is lower than that of a signal transmitted and received by a resonance of the at least one third antenna radiator.

5. The electronic apparatus of claim 2 , wherein the at least one third antenna radiator is included in a sub board electrically connected to the main board.

6. The electronic apparatus of claim 5 , wherein the sub board is divided into a plurality of parts.

7. The electronic apparatus of claim 1 , wherein the at least one first antenna radiator is attached to a non-conductive member fixed to the housing.

8. The electronic apparatus of claim 7 , wherein at least one portion of the feed part passes through the non-conductive member.

9. The electronic apparatus of claim 7 , wherein the non-conductive member does not overlap the main board.

10. The electronic apparatus of claim 1 , wherein the at least one second antenna radiator does not overlap the feed part.

11. The electronic apparatus of claim 1 , wherein the at least one second antenna radiator is disposed inside or outside of the housing.

12. The electronic apparatus of claim 1 , wherein the at least one second antenna radiator constitutes at least one portion of the housing and includes at least one of a plurality of separated metal parts.

13. The electronic apparatus of claim 1 , wherein the at least one second antenna radiator includes at least one metal part that is fixed to an injection-molded plastic part when the housing is shaped through insert injection molding.

14. The electronic apparatus of claim 1 , wherein the at least one second antenna radiator has a closed-loop.

15. The electronic apparatus of claim 1 , wherein the at least one second antenna radiator includes a plurality of slots.

16. The electronic apparatus of claim 1 , wherein the housing comprises:
a front case disposed at a front side of the electronic apparatus; and
a rear case disposed at a rear side of the electronic apparatus and coupled to the front case.

17. The electronic apparatus of claim 16 , wherein the at least one second antenna radiator is disposed inside or outside of the front case of the housing.

18. The electronic apparatus of claim 16 , wherein the at least one second antenna radiator is disposed inside or outside of the rear case of the housing.

19. The electronic apparatus of claim 1 , wherein the at least one first connection member or the at least one second connection member includes at least one of a conductive tape, a C-clip, a pogo-pin, and solder.

20. An electronic apparatus comprising:
a mounting plate including at least one metal part;
a rear case coupled to the mounting plate;
a battery cover coupled to the rear case;
a main circuit board disposed between the mounting plate and the rear case;
a sub circuit board received in the mounting plate and electrically connected to the main circuit board;
an antenna radiator disposed between the mounting plate and the rear case;
at least one first connection member for electrically connecting the at least one metal part to the antenna radiator;
at least one second connection member for electrically connecting the at least one metal part to a ground part formed on the main circuit board; and
a feed part extending from the main circuit board and disposed between at least one portion of the antenna radiator and at least one portion of the sub circuit board,
wherein the antenna radiator and the at least one metal part indirectly receive an electric current from the feed part and resonate to transmit and receive a signal of first frequency band, and
wherein at least one portion of the sub circuit board indirectly receives an electric current from the feed part and resonates to receive and transmit and receive a signal of second frequency band.
