あった。"Problem to be solved by the invention" By the way, in the above-mentioned non-contact automatic ticket gate device,
An unspecified number of passengers carry the IC card 3, and these passengers transfer the IC card 3 to the communication device 1 of the ticket gate.
, it is assumed that the planar antenna 4 of the IC card 3 approaches the planar antenna 2 of the communication device 1 at any angle, so communication can always be performed reliably regardless of the relative angle. required to be able to do so. However, when transmitting and receiving data using the planar antennas 2 and 4 described above, the planar antennas 2 and 4
Improvements have been desired since the communication range varies depending on the relative angle. In other words, when the frequency of radio waves used for communication is below IMHz, when the flat antenna 4 of the IC card 3 is parallel to the flat antenna 2, as shown in FIG. Therefore, a uniform communication range A is obtained, and if the IC card 3 is brought close to the planar antenna 2, communication is always possible. Conversely, as shown in FIG.
When A is vertical, the communicable range A is 2
Even if the IC card 3 is divided and spread laterally and the IC card 3 is brought closer to the planar antenna 2, communication may become impossible, especially at the center of the planar antenna 2. As described above, there is a restriction in usage that if the IC card 3 is oriented in a specific direction, it must be used with consideration to the possibility that communication will be impossible.
