Abstract

PURPOSE:To improve the yield and to reduce the cost of an assembling jig by forming a tapered transmission line at a conversion part between a microstrip and a triplate of a feed-through part. CONSTITUTION:A tapered pattern is formed for a transmission line 1 at a conversion part between a microstrip and a triplate 13. Then the taper parts 11 and 12 are secured on the line 1 at a feed-through part. The equivalent circuits of both parts 11 and 12 consist of combinations of countless distribution constant lines 4 and capacitors 5. In this respect, only the constants of some of those numerous elements (lines 4 and capacitors 5) are changed even if some positional error is produced between both substrates 2a and 2b when they are joined together. As a result, the changing rate of the matching state is reduced despite a positional error caused when two substrates are joined together. Thus the yield is improved and the cost of an assembling jig is reduced.
