<p><P>PROBLEM TO BE SOLVED: To obtain a feeder circuit which is hardly affected by a use environment, capable of suppressing variations in radiation characteristics, and capable of being used in a wide frequency band. <P>SOLUTION: The feeder circuit is arranged between feeder terminals 42a and 42b and a radiation plate, and supplies a transmission signal to the radiation plate and/or is supplied with a received signal from the radiation plate. The feeder circuit includes a resonant circuit and/or a matching circuit that includes inductance elements L1 and L2. The inductance elements L1 and L2 are helically formed with being wound in opposite directions and connected to each other so as to be conductive in DC. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
