Claim 12:
13. A communication method implemented using a wireless communication apparatus that includes a first conductor having four or more vertices, a second conductor having four or more vertices, a third conductor having four or more vertices, and a fourth conductor having four or more vertices, the communication method comprising:
performing, using the first conductor and the second conductor as a set of electrodes, wireless communication of a differential signal using electric field coupling, between the wireless communication apparatus and another wireless communication apparatus; and
performing, using the third conductor and the fourth conductor as another set of electrodes, wireless communication of a differential signal using electric field coupling, between the wireless communication apparatus and the another wireless communication apparatus,
wherein a degree of coupling between the first conductor and the third conductor is larger than a degree of coupling between the first conductor and the fourth conductor,
wherein a degree of coupling between the second conductor and the third conductor is larger than a degree of coupling between the second conductor and the fourth conductor, and
wherein a first straight line connecting a centroid of the first conductor and a centroid of the second conductor is not parallel to a second straight line connecting a centroid of the third conductor and a centroid of the fourth conductor.
