MTT-4, pp. 4–8, Jan. 1956. 1 Introduction In order to accomplish an analytical study of several microstrip passive circuits, an introduction to some basic concepts will be given here. First, as a starting point, a small review of the transmission line theory is given. Then, one simple transmission line section (as a building block), two impedance transformers, one low-pass filter, and one combiner/divider device are all consecutively examined.
782 cm) is increased or decreased. By running this option a very sensible variation of the real and imaginary impedance magnitudes, even for small increments of lcf (1 × 10 –6), is observed. Because of this, very large impedance values (opencircuits) can arise, mandating an adjustment of the magnitudes in order to put all the responses in the same scale. There is not a simple criterion for choosing this adjustment, but one judicious selection must be based on the knowledge of the microstrip characteristic impedances, which can be used as normalization or transformation values.
