13. Why is single stub matching inaccurate on coaxial line? For a coaxial line, it is not possible to determine the location of a voltage minimum without a slotted line section, so that the placement ofa stub is extremely difficult at the required point. Hence the single stub matching is inaccurate on a coaxial line. 14. There are two design parameters for single stub matching: The location of the stub with reference to the load dstub The length of the stub line Lstub Any load impedance can be matched to the line by using single stub technique.
