PROBLEM TO BE SOLVED: To fully prevent mutual interference even if many radio machines are operated simultaneously without making a circuit configuration complex. SOLUTION: Transmission waves from the radio machine 10 are outputted from a second port (b) of a first circulator 11, are totally reflected by a first BEF 22, are inputted to the second port (b), are outputted from a third port (c), and are inputted to a second circulator 14. The transmission waves in which transmission noise components are removed are transmitted from an antenna 17 through the second circulator 14. The reception waves received by the antenna 17 are outputted from the second port (b) of the second circulator 14, are totally reflected by a second BEF 25, are inputted to the second port (b), are outputted from a first port (a), and are inputted to the first circulator 11. Reception waves in which interference wave components are removed are received by the radio machine 10 through the first circulator 11. COPYRIGHT: (C)2005,JPO&NCIPI |
