Portable wireless device with expandable mechanism and wireless communication method
View Patent ↗A portable wireless device and a wireless communication method, which can transmit and receive wireless signal without affecting influence from metallic part that is included in an expandable mechanism, are provided. In the portable wireless device taking two statuses of an expanded status in which an upper housing 2 and a lower housing 7 are arranged approximately in series and a contracted status in which the upper housing 2 and the lower housing 7 are overlapped each other, at least a part of rotating mechanism 1 which makes the expanded status and the contracted status variable is formed of metal, and the metal part of rotating mechanism 1 operates as an antenna.
1. A portable wireless device taking two statuses of an expanded status in which a first and a second housing are located approximately in series and a contracted status in which said first and second housing overlap,
wherein at least a part of an expandable mechanism, which makes variable said expanded status and said contracted status, is formed of metal,
wherein a metal part of said expandable mechanism and a first substrate arranged in said first housing operate as a tabular reverse F antenna,
wherein said expandable mechanism is electrically disconnected from a second substrate arranged in said second housing, and
wherein said metal part operating as said tabular reverse F antenna is located at a center point between said first and second housing at said expanded status.
2. The portable wireless device according to claim 1 comprising:
a first joint part supplying antenna current from said first substrate arranged in said first housing to said metal part of said expandable mechanism; and
a second joint part connecting said metal part of said expandable mechanism with a ground of said first substrate.
3. The portable wireless device according to claim 2 , wherein
said first substrate and said second substrate arranged in said second housing are connected via a cable.
4. The portable wireless device according to claim 1 , wherein
said expandable mechanism is a hinge mechanism that connects said first housing with said second housing freely and rotationally so as to expose in said expanded status a face which is concealed in said contracted status.
5. The portable wireless device according to claim 1 , wherein
said expandable mechanism is a sliding mechanism that connects said first housing with said second housing so as to slide mutually.
6. The portable wireless device according to claim 1 , wherein
said expandable mechanism is a rotating mechanism that connects said first housing with said second housing freely and rotationally so as to expose in said expanded status a face of a housing which is concealed by the other housing in said contracted status.
7. A wireless communication method using a portable wireless device taking two statuses of an expanded status in which a first and a second housing are located approximately in series and a contracted status in which said first and said second housing overlap, comprising;
forming at least a part of an expandable mechanism, which makes variable said expanded status and said contracted status, using metal,
wherein a metal part of said expandable mechanism and a first substrate arranged in said first housing operate as a tabular reverse F antenna,
wherein said expandable mechanism is electrically disconnected from a second substrate arranged in said second housing, and
wherein said metal part operating as said tabular reverse F antenna is located at a center point between said first and second housing at said expanded status.
