Title:
RADIO COMMUNICATION MODULE, RADIO COMMUNICATION DEVICE, AND RADIO COMMUNICATION TERMINAL
Document Type and Number:
WIPO Patent Application WO/2011/108339
Kind Code:
A1
Abstract:
In order to obtain a radio communication module, a radio communication device, and a radio communication terminal in which the accuracy of the position of a feed circuit board with respect to an antenna pattern can be relaxed and production efficiency can be improved, a radio communication device equipped with a radio IC chip (10) that processes a radio signal, a feed circuit board (15) that includes a loop electrode (20) and an auxiliary electrode (26) that are electrically connected to the radio IC chip (10), and an antenna pattern (35) that is electromagnetically coupled to the loop electrode (20) and the auxiliary electrode (26) is disclosed. The loop electrode (20) comprises wound coil patterns and is arranged in a manner such that at least a portion thereof overlaps the antenna pattern (35) in plan view. The auxiliary electrode (26) is arranged in a manner such that at least a portion thereof overlaps the loop electrode (20) and the antenna pattern (35) in plan view. At least one dividing slit is formed in the auxiliary electrode (26) and positioned in a manner such that at least one of said slits does not overlap the antenna pattern (35).
