6. The portable terminal apparatus as claimed in claim 1, wherein said antenna is a flat cable antenna.
7. The portable terminal apparatus as claimed in claim 6, wherein said flat cable is arranged so as to be upright to a bottom surface of said housing.
8. The portable terminal apparatus as claimed in claim 7, wherein a position defining part is provided to said housing so as to define a position of said antenna.
9. The portable terminal apparatus as claimed in claim 2, wherein a position defining part is provided to said housing so as to define a position of said antenna.
10. The portable terminal apparatus as claimed in claim 3, wherein a position defining part is provided to said housing so as to define a position of said antenna.
11. The portable terminal apparatus as claimed in claim 6, wherein a position defining part is provided to said housing so as to define a position of said antenna.
FIG. 3 is an enlarged view of the antenna 5 incorporated in the portable terminal apparatus 1. Conventionally, the antenna 5 built in the portable terminal apparatus 1 uses a multilayer flexible board, and an antenna wiring 11 formed on a base member 10. The antenna wiring 11, which serves as an antenna, constitutes a helical antenna by being patternized in a spiral shape. Each end of the antenna wiring 11 is extended to a connector part 12, and the connector part 12 is connected to the printed circuit board 6. It should be noted that an opening part 10a is formed in a central part of the base member 10 as shown in FIG. 3.
The antenna 5 having the above-mentioned structure is stuck on a bottom surface 4a of the housing 4 as shown in FIG. 2. The antenna 5 is stuck on the bottom surface 4a in a state where the plane of the antenna 5 matches the plane of the bottom surface 4a, that is, the antenna 5 and the bottom surface 4a are parallel to each other. Moreover, the arranged position of the antenna 5 is determined to be at a part where the density of the electronic parts is small on an individual type of the portable terminal apparatus basis. The arranged position of the antenna 5 is selected to be a side part of the speaker 8 in the example shown in FIG. 1.
As shown in each figure, the body part 22 comprises a battery 21, an antenna 25, a multiplayer printed-wiring board 26, electronic parts 27, etc. that are accommodated in the housing 24 which serves as a case. The lid part (not shown in the figures) is rotatably attached to the body part 23 by a hinge part 23. Moreover, a bottom surface 24a of the housing 24 is provided with a speaker 28 and electrodes 29 for battery charge. The battery 21 (rechargeable battery) is largest in shape among the component parts provided in the housing 24, as shown in FIG. 4.
Furthermore, the antenna 25 having the flat cable structure is arranged so as to surround the battery 21 in a state where the antenna 25 is substantially perpendicular to the plane of the multilayer printed-wiring board 26 (this is equivalent to a state where the antenna 25 is substantially perpendicular to the bottom surface 24a of the housing 24).
FIGS. 7 and 8 shows a connection structure between the antenna 25 and the multilayer printed-wiring board 26. As described above, in the present embodiment, the antenna 25 is arranged upright to the multilayer printed-wiring board 26 (the bottom surface 24a of the housing 24) so as to improve the space efficiency of the antenna 25 in the housing 24.
The terminal A1 of the connector part 32 located at an upper side in FIG. 8 is connected to a via 42a through a wiring pattern 46 formed on the multilayer printed-wiring board 26. The via 42a is connected to an end of an intralayer wiring 40 formed in an inner layer of the multilayer printed-wiring board 26. Additionally, a via 42b is formed on the other end of the intralayer wiring 40, and the via 42b is extended to the surface of the multilayer printed-wiring board 26 and is connected to the terminal A2 of the connector part 32 located at a lower side in FIG. 8 through a wiring pattern 47.
The terminal B1 of the connector part 32 located at an upper side in FIG. 8 is connected to a via 43a through a wiring pattern 48 formed on the multilayer printed-wiring board 26. The via 43a is connected to an end of an intralayer wiring 41 formed in an inner layer of the multilayer printed-wiring board 26. It should be noted that the intralayer wiring 40 and the intralayer wiring 41 are formed in different layers so as to be electrically separated from each other.
Additionally, a via 43b is formed on the other end of the intralayer wiring 41, and the via 43b is extended to the surface of the multilayer printed-wiring board 26 and is connected to the terminal B2 of the connector part 32 at a lower side in FIG. 8 through a wiring pattern 47. Further, the terminal C1 of the connector part 32 located at a lower side in FIG. 8 is connected to the electronic part 27 through a wiring pattern 51 formed on the multilayer printed-wiring board 26. Additionally, the terminal C2 of the connector part 32 located at a lower side in FIG. 8 is connected to the electronic part 27 through a wiring pattern 52 formed on the multilayer printed-wiring board 26.
