Document Type and Number:
Japanese Patent JP3074766
Kind Code:
B2
Abstract:
PURPOSE:To attain signal transmitter without care about wear contactless by arranging plural microstrip lines formed to be ring shape having nearly the same radius opposite to each other at an interval. CONSTITUTION:Dielectric boards 11, 21, 41, 51 and wide conductors 12, 22, 42, 52 are formed to be rings or disks. and they are arranged so that the center axes are substantially coincident with each other, and microstrip lines 4, 5 are turned around the center axis. Thus, narrow conductors 13, 43 and 23, 53 keep a prescribed interval opposite to each other. The narrow width conductors 13, 43 and 23, 53 of lines 1, 2, 4, 5 keep the relation that the are opposite to each other with a prescribed interval, then high frequency coupling is caused among them, that is, coupling between two high frequency transmission lines being the lines 1, 4 and between two high frequency transmission lines being the lines 2, 5, and contactless high frequency transmission of two channels is implemented between them.
