Abstract

PURPOSE:To eliminate a floating volume and realize satisfactory impedance matching over a wide band by changing the dielectric factor of microwave circuit substrate. CONSTITUTION:A microwave circuit substrate 7 has conductive films 8, 8' on the front/back surface and routes 3, 4 connected by ribbons 15, 15'. The both sides of the substrate have dielectric factors epsilon1, epsilon2 respectively and the other parts have an intermediate value between epsilon1 and epsilon2. A volume CT per unit area SO is worked out by height a and height b of the substrate and a distance X from the end of the substrate 1. Route impedance ZO represents a prearranged relationship between an overall dielectric factor epsilonT and a propagation factor of electric wave inside the substrate 7. If a conductive film 8 is formed using this relationship, the route of the substrate 7 shows a condition where the floating volume does not exist, so that it is possible to connect the conductive films 3 and 4 with the floating volume being set at ''0''. For this reason, a satisfactory impedance matching can be obtained over a wide range and a smooth signal propagation realized.
