Electronic device with wireless communication feature
View Patent ↗An electronic device includes a display section and an antenna. The antenna is provided on the back of a display panel within a housing of the display section. The housing of the display section has an opening to surround an area for mounting the antenna. Even with the antenna disposed within the housing of the display section, antenna performance is improved. The electronic device has a reduced size and a higher package density, as well as reliable communications with constant stability.
1. An electronic device, comprising:
a display housing having a display surface and a rear surface opposite to the display surface, the display housing being made of a conductive material, a nonconductive portion being formed in a part of a rear surface;
an antenna placed in the nonconductive portion; and
a communication unit configured to perform wireless communications by using said antenna, wherein said antenna projects outward from said housing.
2. The electronic device according to claim 1 , wherein said nonconductive portion is covered with a cover.
3. The electronic device according to claim 2 , wherein said cover is formed of a nonconductive material.
4. The electronic device according to claim 2 , wherein said cover is removable, and said electronic device further includes a signal output terminal on a signal path between said antenna and said communication unit.
5. The electronic device according to claim 1 , wherein a perimeter length of said nonconductive portion is equal to or longer than one wavelength of a frequency used in wireless communications.
6. The electronic device according to claim 1 , wherein said housing is grounded.
7. The electronic device according to claim 1 , wherein said antenna is provided in a central portion in said nonconductive portion in a width direction.
8. The electronic device according to claim 1 , wherein said antenna is provided in an upper portion in said nonconductive portion in a vertical direction.
9. The electronic device according to claim 1 , wherein said antenna includes an antenna substrate and an antenna element provided on said antenna substrate, said antenna substrate including a printed circuit board formed with a conductive pattern for grounding, and said antenna substrate is connected to said housing.
10. The electronic device according to claim 9 , wherein a perimeter length of the conductive pattern is in a range of about 0.7 to about 1.4 of a wavelength of a frequency used in wireless communications.
11. An electronic device, comprising:
a display housing made of a conductive material, a nonconductive portion being formed in a part of a rear surface of the housing;
a display unit provided in said housing;
an antenna placed in said display housing and facing the nonconductive portion; and
a communication unit configured to perform wireless communications by using said antenna, wherein said antenna projects outward from said housing.
12. An electronic device, comprising:
a housing made of conductive material, a nonconductive portion being formed in a part of a rear surface of the housing;
a display unit provided in a front of said housing;
an antenna positioned between said display unit and said nonconductive portion; and
a communication unit configured to perform wireless communications by using said antenna, wherein said antenna projects outward from said housing.
