Antenna device to be loaded into an information processing apparatus
View Patent ↗An antenna device to be loaded into an information apparatus has an antenna unit composed of antenna members which have a plurality of radio communication frequency bands, and which are divided into two of an element part having a flexural portion and a GND part, and a holding member composed of a member having non-conductivity, such as a resin member, to hold the respective antenna members so as to leave a constant gap g from the antenna members within a window area, the holding member being mounted so as to hang on an edge at the outside of a frame body of a liquid crystal display panel in an LCD housing of a PC.
1. An antenna device to be implemented on a housing of an information processing apparatus, comprising:
an antenna unit including a first antenna member with a flexural portion, and a second antenna member; and
a holding member to hold the antenna unit so as to form a gap between the first antenna member and the second antenna member to be mounted in the housing, the holding member including (i) a window area to expose a region at which the gap is formed and (ii) power feeding regions to which a communication cable for propagating signals received and transmitted is connected.
2. The antenna device according to claim 1 , wherein the holding member is positioned further away from the housing than both the first antenna member and the second antenna member and holds the first antenna member and the second antenna member so as to cover the flexural portion of the first antenna member.
3. The antenna device according to claim 2 , further comprising a plurality of fixing parts formed at the holding member, the fixing parts being fitted into a plurality of apertures formed in the first antenna member and the second antenna member to hold the antenna unit in a predetermined position.
4. The antenna device according to claim 2 , wherein the holding member is fixed to a position of the housing at which a frame body of the display unit and a region arranged to leaving the gap do not overlap with each other when the display unit of the computer is installed.
5. The antenna device according to claim 4 , comprising
at least two or more fixing parts provided at arbitrary positions on an inner face of the housing of the computer in order for fixing the holding member at the position of the housing.
6. The antenna device according to claim 5 , wherein the fixing parts are fitted into apertures provided at regions except for regions to which the antenna members are in contact with the holding member and the window area.
7. The antenna device according to claim 2 , wherein the holding member includes a notched portion formed from the window area with the communication cable wired on the notched portion.
8. The antenna device according to claim 2 , wherein the holding member includes a guide member which is formed so as to elongate from the window area in parallel with the arranging direction of the two antenna members, and the communication cable are wired along the guide member.
9. The antenna device according to claim 1 , wherein the holding member further comprises a reinforcing part to reinforce the holding of the flexural portion of the first antenna member, the reinforcing part being formed so as not to overlap with a display unit at the time of mounting in the housing of the computer.
10. The antenna device according to claim 9 , wherein the holding member is provided with an aperture penetrating through the reinforcing part, and the communication cable is wired so as to pass through the aperture.
11. The antenna device according to claim 1 , wherein the holding member includes a guide member which is formed so as to cover the flexural portion of the first antenna member from the outside, and to elongate from the window area in parallel with the arranging direction of the two antenna members, and which is formed so as not to overlap with the first antenna member and the second antenna member, and
the communication cable are wired along the guide member.
12. An antenna device implemented on a side housing for liquid crystal display panel of a computer, comprising:
an antenna unit including a first antenna member and a second antenna member, a notched side of the first antenna member being separated from second antenna member by a substantially constant gap; and
a holding member to secure the first antenna member and the second antenna member and to maintain the gap between the first and second antenna members, the holding member including a window area to expose a region at which the gap is formed.
13. The antenna device according to claim 12 , wherein the holding member further includes power feeding regions to which a communication cable for propagating signals received and transmitted by the antenna device is connected.
14. The antenna device according to claim 12 , wherein the holding member is positioned with the first and second antenna members between the holding member and an interior of the housing.
15. The antenna device according to claim 14 , wherein the holding member further comprises a reinforcing part to reinforce holding of a flexural portion of the first antenna member, the reinforcing part being formed so as not to be overlapped by the liquid crystal display panel at the time of mounting in the housing of the computer.
16. The antenna device according to claim 15 , wherein the holding member is provided with an aperture penetrating through the reinforcing part where the communication cable is wired so as to pass through the aperture.
17. The antenna device according to claim 14 , wherein the holding member includes a guide member that does not overlap both the first antenna member and the second antenna member and the communication cable being wired along the guide member.
