Embodiment Construction

[0024] First, a wireless transmission / reception card according to the present invention will be explained. According to the present invention, the wireless sending / receiving card has at least one rod-shaped antenna for wireless sending and receiving, and the length direction of the rod-shaped antenna is substantially parallel to the main surface of the wireless sending / receiving card. It should be noted here that the main surfaces of the card mean the two surfaces having the largest areas among the six surfaces of the card substantially in the shape of a rectangular parallelepiped.

[0025] FIG. 1 shows a perspective external view of a wireless sending / receiving card according to the present invention. The wireless transmission / reception card 1 shown in FIG. 1 has two rod antennas 2 and 3 for transmission and reception by a diversity method. The length directions of the rod antennas 2 and 3 are substantially parallel to the main surface of the wireless transmission / reception ...

Abstract

A wireless transmission / reception card has a pole-shaped antenna for wireless transmission and reception, and the length direction of the antenna is substantially parallel to the main faces of the card. A headset has a slot in which the wireless transmission / reception card is inserted, and, when the card is inserted in the slot, the pole-shaped antenna of the card is set upright substantially in the vertical direction in the normal use state of the headset. The wireless transmission / reception card excels in portability, and, when inserted in the slot of the headset, helps enhance the antenna gain in the horizontal plane in the normal use state.

Description

[0001] This nonprovisional application claims priority under 35 U.S.C. §119(a) to Patent Application No. 2003-109292 filed in Japan on April 14, 2003, the entire contents of which are incorporated herein by reference content. technical field [0002] The present invention relates to a wireless transmission module, such as a wireless transmission / reception card, used as a part of a wireless network system allowing wireless transmission of AV streams, IP data, and the like. Background technique [0003] In recent years, wireless network systems have become increasingly common. An example of a wireless mobile terminal serving as a part of such a wireless network system is a notebook personal computer 101 having connected thereto a wireless LAN card 100 operating in the 2.4 GHz band, as shown in FIG. 7 . The wireless LAN card 100 includes a plug-shaped internal antenna 102, and is connected to the notebook personal computer 101 in such a manner that the main surface of the card...
