PURPOSE:To eliminate a gap between bases and to prevent the resonance by interposing a conductive elastic or plastic member to a position corresponding to a microstrip line connecting between adjacent bases. CONSTITUTION:Units 18, 19 are fixed on a conductive case 40 by a screw 20 in a slightly parted state of bases 10, 11. The gap 42 between the bases 10, 11 is packed with the conductive elastic or plastic member 41 such as a rubber mixed with carbon powder. The conductive member 41 is provided on a corresponding position to the end of the microstrip lines 16, 17 connected together and provided on the gap 42 over a range being nearly three times the width of the microstrip lines 16, 17 or over. The ends of the microstrip lines 16, 17 are connected by a gold ribbon 21 at the upper part of the conductive member 41. Since the gap 42 between the bases 10, 11 is buried by the conductive member 41 in this way, the occurrence of resonance is completely prevented. |
