<p>In a radio guidance antenna, in which the sum of mutual inductances of antennas is small and which is inexpensive and excellent in quality of communication, a data communication method, and a non-contact data communication apparatus, which make use of the antenna, a first antenna is divided into upper and lower half regions by antenna conductors, a second antenna is composed of an antenna conductor and formed on the same plane as or a plane parallel to a plane of the first antenna, the second antenna being not to connected to the first antenna at any points where it intersects the first antenna, and inductively coupled to the upper and lower halves of the first antenna through regions, the first antenna is supplied with electric power from a first feeding point, and the second antenna is supplied with electric power from a second feeding point. <IMAGE> <IMAGE></p> |
