PURPOSE:To secure the assured mechanical seal-up degree and the electric shielding and thus stabilize the characteristics as well as increase the mass productivity, by connecting plural units of independent resonators featuring the same measurement via the cable of 1/4 wavelength of the resonance frequency. CONSTITUTION:Coaxial resonators 8, 9 and 10, which are shielded electrically excepting the cable connection part and also sealed up mechanically, are connected with cables 2 and 3 featuring the length of 1/4 wavelength of the resonance frequency and via capacity elements 5, 6 and 7 each. The device thus constituted is provided at both the transmission and reception sides each to be connected to the antenna at the side of terminal 11 along with the side of terminal 12 connected to the transmission and reception terminals each. |
