Abstract

PURPOSE:To form an impedance converter which is small in size and less in reflecting waves, by folding a coaxial line in the impedance converter. CONSTITUTION:Coaxial lines A(1), B(2) are coaxial lines with different shape and impedance characteristics. External wall of cylindrical grooves provided at a part of an inner conductor A(3) and that of an external conductor B(6) form a folding coaxial line 11. Thus, waves of radial electric field components incident from the line A(1) propagate as the waves toward the same direction to the line B(2) via the line 11. Said folding coaxal line 11 is taken as L4 in length, about 1/4 wavelength, the characteristic impedance is suitably set, allowing to form the impedance converter less in the reflection wave with small size. Two or more foldings enable small size.
