<P>PROBLEM TO BE SOLVED: To provide a communication method using a different frequency band that can secure relatively high communication quality without preventing transmission of communication power as much as possible. <P>SOLUTION: A termination circuit 70 is provided at the end of branch lines 21 and 22. The termination circuit 70 is shunt-connected to an outlet 41. The termination circuit 70 has a filter 73 and a circuit element 74. The filter 73 blocks signals in a first frequency band and transmits signals in a second frequency band. Impedance of the circuit element 74 is adjusted so as to prevent generation of a reflection wave at the end of the branch line 21 or 22. <P>COPYRIGHT: (C)2012,JPO&INPIT |
