<P>PROBLEM TO BE SOLVED: To downsize an antenna part. <P>SOLUTION: Antenna parts 10 are provided to a parent module 101 and child modules 111 and 112 each on surfaces thereof opposite to a communication parter when performing a radio communication. The antenna part 10 has on a base plate thereof a linear antenna element arranged and formed in a folded state to connect with a first feeding point and a second feeding point so as not to intersect nor contact with its own on a path connecting the first feeding point and the second feeding point. An antenna part 10a of the parent module 101 and an antenna part 10e of the child module 111 have the antenna elements of the same shape plane-symmetrically, and the antenna 10a and the antenna 10e are made to closely face to each other to communicate data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
