Abstract

An electronic apparatus is provided. The electronic apparatus includes a housing including a first portion and a second portion different from the first portion, a keyboard disposed in the first portion of the housing, a palm rest disposed in the second portion of the housing and a rest area, and an antenna disposed inside the housing so as to overlap the palm rest. The antenna includes a feed pattern disposed in a rest area away from the keyboard, the feed pattern including a first ground area connected to the housing, and a feed area connected to the first ground area, a grip sensing pattern disposed in the rest area adjacent to the keyboard, the grip sensing pattern including a second ground area connected to the housing and a coupling area connected to the second ground area and configured to be coupled to the feed area.

First claim

What is claimed is:

1 . An electronic device comprising:
a housing comprising a first portion and a second portion different from the first portion; a keyboard disposed in the first portion of the housing; a palm rest disposed in the second portion of the housing and comprising a rest area; and an antenna disposed in the housing to overlap the palm rest, wherein the antenna comprises:
a feed pattern disposed in the rest area away from the keyboard, the feed pattern comprising a first ground area connected to the housing, and a feed area connected to the first ground area, and
a grip sensing pattern disposed in the rest area adjacent to the keyboard, the grip sensing pattern comprising a second ground area connected to the housing, and a coupling area connected to the second ground area and configured to be coupled to the feed area.

2 . The electronic device of claim 1 , wherein a number of rest areas is more than one, a plurality of the rest areas is arranged in a direction away from the keyboard, and the antenna has sensitivity that decreases along the direction away from the keyboard.

3 . The electronic device of claim 1 , wherein a number of rest areas is more than one, a plurality of the rest areas are arranged in a direction away from the keyboard, and the antenna has grip sensing ranges that decrease along the direction away from the keyboard.

4 . The electronic device of claim 1 ,
wherein the first portion comprises a first side area, and a second side area opposite to the first side area, and the housing further comprises a communication module disposed in the second side area, and wherein the second portion comprises a third side area on a same side as the first side area, and a fourth side area opposite to the third side area and on the same side as the second side area, and the antenna is disposed in the fourth side area.

5 . The electronic device of claim 1 , wherein at least one ground area of the first ground area and the second ground area faces a central area of the second portion and comes into contact with the housing.

6 . The electronic device of claim 1 , wherein the feed area and the coupling area are physically separated from each other.

7 . The electronic device of claim 1 , further comprising:
a sensor; and a transmission line configured to connect the sensor and the coupling area, wherein the antenna further comprises a connection area, to which the transmission line is connected, and an inductor configured to connect the connection area and the coupling area, and/or wherein the transmission line comprises a ground portion that comes into contact with the housing.

8 . The electronic device of claim 1 , wherein the antenna further comprises a capacitor configured to connect the coupling area and the second ground area.

9 . The electronic device of claim 1 , wherein the palm rest comprises a radiating opening that at least partially overlaps the antenna.

10 . The electronic device of claim 1 , further comprising a speaker disposed between the palm rest and the antenna.

11 . The electronic device of claim 1 , further comprising a cooling module configured to reduce heat from at least one portion of the electronic device.

12 . The electronic device of claim 1 , further comprising a heat plate configured to absorb heat from at least one portion of the electronic device.

13 . The electronic device of claim 1 ,
wherein the antenna is a first antenna configured to operate in a first frequency band, and wherein the electronic device further comprises a second antenna configured to operate in a second frequency band different from the first frequency band, and disposed in the housing to be coupled with the grip sensing pattern.

14 . The electronic device of claim 13 , wherein the second antenna and the coupling area are physically separated from each other.

15 . The electronic device of claim 13 , wherein the second antenna is configured to transmit a signal in the second frequency band while the first antenna transmits a signal in the first frequency band.

16 . The electronic device of claim 13 ,
wherein the first portion comprises a first side area, and a second side area opposite to the first side area, and the housing further comprises a communication module disposed in the second side area, wherein the second portion comprises a third side area on a same side as the first side area, and a fourth side area opposite to the third side area and on the same side as the second side area, and the first antenna and the second antenna are disposed in the fourth side area, and/or wherein the second antenna is disposed between the communication module and the first antenna.

17 . An antenna for an electronic device of claim 1 comprising a second antenna configured to operate in a second frequency band different from a first frequency band of a first antenna.
