[0027] FIG. 1 shows an antenna module according to a first embodiment of the present invention. The antenna module of this embodiment comprises a flexible printed board (hereinafter referred to as "FPC substrate") 1 (which is made of a flexible material such as polyimide), an antenna 2 provided on the FPC substrate 1, impedance matching The inductor 3 used, the coaxial connector 4 used to connect the antenna 2 with a separate transmitting / receiving circuit module through a coaxial cable, the ground conductor 5 made of a conductive pattern, and the back of the FPC substrate 1 Reinforcement plate 6 made of epoxy glass steel plate provided above.
[0028] A chip antenna that can be used as the antenna 2 may have a particularly small cuboid shape with a cross-sectional size of several millimeters by several millimeters and a length of 1 centimeter or less. Specifically, a rectangular parallelepiped-shaped small insulating chip serving as a conductor of an antenna pattern is wound...

[0048] Figure 4 A notebook personal computer is shown as a second embodiment of the present invention, which includes multiple antennas to accommodate multiple wireless communication schemes. As the plurality of schemes, described here are the IEEE802.11b scheme for wireless LAN (Local Area Network) and the short-distance wireless communication scheme "Bluetooth" scheme, both of which are used in the 2.4 GHz frequency band. For the IEEE802.116 solution, two antennas are used to provide a diversity antenna to reduce the influence of reflected waves.
[0049] The liquid crystal display unit 30 is pivotally mounted on the distal end of the main body 33 of the notebook type personal computer through the hinge 25 . Three FPC substrates 1A to 1C are mounted at one end (upper end of the liquid crystal panel) inside the cabinet of the display unit 30 . FPC substrates 1A and 1B have IEEE802.11b scheme diversity antennas 2A and 2B respectively mounted thereon, while FPC substrate 1C ...

[0082] Figure 11 A notebook type personal computer is shown as a third embodiment of the present invention, which includes multiple antennas for multiple wireless communication schemes. As a plurality of communication schemes, described here are the wireless LAN IEEE802.11a for the 5GHz band and the short-distance wireless communication scheme "Bluetooth" scheme. For the IEEE802.11a scheme, two antennas are used to provide a diversity antenna to reduce the influence of reflected waves.
[0083] The crystal display unit 30 is mounted on the far end of the main body 33 of the notebook personal computer via a hinge 25 . Three FPC substrates 1D, 1C and 1E are mounted at one end (upper end of the liquid crystal panel) inside the cabinet of the display unit 30 . FPC substrates 1D and 1E have IEEE802.11a diversity antennas 2D and 2E mounted thereon respectively, while FPC substrate 1C has "Bluetooth" 2C mounted thereon. In other words, the FPC substrate 1C for the "Bluetooth" ant...
