Electronic device and method of mounting radio antenna

1. An electronic device comprising:

a body; and

a display unit connected to the body, the display unit comprising:

first and second antennas for a first radio communication scheme which uses a diversity scheme provided at an upper portion of the display unit; and

a third antenna for a second radio communication scheme provided between the first and second antennas, the third antenna being arranged at a position close to the second antenna than the first antenna,

wherein the first antenna includes a transmission/reception antenna and the second antenna includes a reception antenna.

2. The electronic device according to claim 1 , wherein the body includes a keyboard, and the display unit is attached to the body to be movable between a closed position at which the display unit covers the keyboard and an open position at which the keyboard is exposed.

3. The electronic device according to claim 2 , wherein the body comprises a first transmission/reception circuit connected to the first antenna and second antennas and a second transmission/reception circuit connected to the third antenna.

4. An electronic device comprising:

a body; and

a display unit connected to the body, the display unit comprising:

first and second antennas for a first radio communication scheme which uses a diversity scheme, the first and second antennas provided at an upper portion of the display unit;

a third antenna for a second radio communication scheme arranged between the first and second antennas; and

a fourth antenna for the second radio communication scheme connected to the second communication module and provided at the upper portion of the display unit,

wherein the second radio communication scheme uses a diversity scheme, the first antenna includes a transmission/reception antenna, the second antenna includes a reception antenna, the third antenna includes a transmission/reception antenna, and the fourth antenna includes a reception antenna.

5. The electronic device according to claim 4 , wherein the first antenna is arranged between the third and fourth antennas.

6. The device according to claim 4 , wherein the body includes a keyboard, and the display unit is attached to the body to be movable between a closed position at which the display unit covers the keyboard and an open position at which the keyboard is exposed.

7. The electronic device according to claim 4 , wherein the body comprises a first transmission/reception circuit connected to the first and second antennas and a second transmission/reception circuit connected to the third and fourth antennas.
