Portable terminal
A portable terminal may include a terminal body, a printed circuit board having a ground unit coupled to an antenna, and an electric field reducing unit to transfer a current flowing in the ground unit to a side surface of the terminal body and to reduce strength of an electric field.
1. A portable terminal comprising:
a terminal body having a receiver at a first end of the terminal body;
a display located on a surface of the terminal body;
a printed circuit board having a ground unit coupled to an antenna disposed at a second end of the terminal body, wherein a portion of the printed circuit board is overlapped by the display; and
an electric field reducing unit to couple to the ground unit, to transfer a current flowing in the ground unit to a side of the terminal body and to reduce strength of an electric field formed at the receiver,
wherein the electric field reducing unit comprises:
a connecting portion configured to couple to a side of the printed circuit board, and
an extending portion formed at the side of the printed circuit board with a predetermined distance therebetween, the extending portion to extend from the connecting portion in a direction away from the receiver.
2. The portable terminal of claim 1 , wherein the antenna comprises an internal antenna mounted at the second end of the terminal body.
3. The portable terminal of claim 1 , wherein the extending portion is formed in a lengthwise direction parallel to the printed circuit board.
4. The portable terminal of claim 1 , wherein the connecting portion is a Flexible Printed Circuit Board (FPCB), and the extending portion is a key plate that includes a switch to enable inputting of information by a push operation.
5. The portable terminal of claim 1 , wherein the antenna to transmit and receive an electric wave having a prescribed wavelength, and the electric field reducing unit has a length corresponding to ¼times of the prescribed wavelength.
6. The portable terminal of claim 1 , wherein the extending portion longitudinally extends from the connection portion and such that the predetermined distance is between the extending portion and the side of terminal body.
7. A portable terminal comprising:
an antenna to receive a signal;
a receiver to output an audio sound based on the received signal;
a terminal body to support the receiver disposed at a first end of the terminal body and the antenna disposed at a second end of the terminal body, the terminal body having a side that extends in a longitudinal direction;
a circuit board to couple to the antenna and to the receiver, wherein at least a portion of the circuit board is overlapped by a display provided on a surface of the terminal body; and
an electric field reducing unit to couple to the circuit board, and to receive current from the circuit board, wherein the electric field reducing unit includes:
a first portion to couple to the circuit board; and
a second portion formed at the side of the printed circuit board with a predetermined distance therebetween, the second portion to extend from the first portion in the longitudinal direction along the side of the terminal body.
8. The portable terminal of claim 7 , wherein the electric field reducing unit receives the current from the circuit board and reduces an electric field strength about the receiver.
9. The portable terminal of claim 7 , wherein the second portion is formed in a lengthwise direction parallel to the circuit board.
10. The portable terminal of claim 7 , wherein the first portion is a Flexible Printed Circuit Board (FPCB), and the second portion is a key plate that includes a switch to enable inputting of information by a push operation.
11. The portable terminal of claim 7 , wherein the antenna to transmit and receive an electric wave at a prescribed wavelength, and the second portion of the electric field reducing unit has a length corresponding to ¼times of the prescribed wavelength.
