<p>The present invention relates to a class of adjustable microstrip and stripline tuners. An exemplary tuner comprises a pair of tuning elements (101, 102), where each tuning element comprises a pair of parallel spaced-apart conductive strips (121, 141; 122, 142) of equal length and at least one movable bridging wire (191, 192) connecting the two strips. The movement of the bridging wire will vary the output impedance of the tuning element, and a complementary arrangement of a pair of tuning elements will form a tuner capable of matching any impedance falling within the Smith chart. </p> |
