Abstract

Information equipment according to an embodiment includes a display housing with a display unit, a first radio communication antenna disposed at an end part of the display housing, a second radio communication antenna using a frequency band adjacent to or overlapped with that of the first radio communication antenna, and a third radio communication antenna disposed at an end part between the first and the second radio communication antennas, and uses a frequency band not adjacent to nor overlapped with those of the first and the second radio communication antennas.

Claims

1. Information equipment comprising:

a housing;

a first antenna arranged on the housing, configured and arranged to make a radio communication in a first frequency band;

a second antenna arranged on the housing, configured and arranged to make a radio communication in a second frequency band adjacent to the first frequency band of the first antenna; and

a third antenna arranged on the housing between the first antenna and the second antenna, configured and arranged to make a radio communication in a third frequency band not adjacent to the first frequency band or the second frequency band.

2. The information equipment of claim 1, wherein

the first antenna makes a radio communication via a wireless LAN;

the second antenna makes a radio communication in a ultra wide band; and

the third antenna is an antenna for a cellular system.

3. Information equipment comprising:

a housing;

a first radio communication antenna arranged on the housing, and configured and arranged to perform transmission and reception in a first frequency band;

a second radio communication antenna arranged on the housing, and configured and arranged to perform transmission and reception in a second frequency band differing from the first frequency band; and

a third radio communication antenna arranged on the housing between the first radio communication antenna and the second radio communication antenna, and configured and arranged to perform reception in the second frequency band.

4. The information equipment of claim 3, wherein the second radio communication antenna is an antenna for a wireless LAN capable of performing transmission and reception;

and

the third radio communication antenna is an antenna for a wireless LAN capable of performing reception.

5. The information equipment of claim 4, wherein, in use, the first radio communication antenna makes a radio communication via the wireless LAN;

and

the second radio communication antenna makes a radio communication in a ultra wide band.

6. Information equipment comprising:

a housing;

a first antenna arranged on the housing, configured and arranged to make a radio communication in a first frequency band;

a second antenna arranged on the housing, configured and arranged to make a radio communication in a second frequency band overlapped with the first frequency band of the first antenna; and

a third antenna arranged on the housing between the first antenna and the second antenna, configured and arranged to make a radio communication with a third frequency band not overlapped with the first frequency band and the second frequency band.
