  • Transmission lines are needed for connecting various circuit elements and systems together. Open-wire and coaxial lines are commonly used for circuits operating at low frequencies. On the other hand, coaxial line, stripline, microstrip line, and waveguides are employed at radio and microwave frequencies. Generally, the lowfrequency signal characteristics are not affected as it propagates through the line. However, radio frequency and microwave signals are affected signi®cantly because of the circuit size being comparable to the wavelength...

  • Lowpass and Bandpass Filters Conventional microstrip lowpass and bandpass filters such as stepped-impedance filters, open-stub filters, semilumped element filters, end- and parallel-coupled half-wavelength resonator filters, hairpin-line filters, interdigital and combline filters, pseudocombline filters, and stub-line filters are widely used in many RF/microwave applications. It is the purpose of this chapter to present the designs of these filters with instructive design examples.
