Design and performance analysis of radio frequency meandered-line microstrips

In the design of miniature microstrip transmission lines, a meandered line is often used as an effective method to insert proper electrical delay while reducing the feature size. However, this design technique also introduces undesirable noise to the applied network. In order to provide detailed analysis regarding the electrical response from variously shaped meandered lines, eight different structures of meandered line microstrip, all of the same physical length of 125 mm, were designed, modeled and characterized in terms of their electrical properties and footprints. Both the simulations and measurements of these microstrip lines were carried out in a frequency range of 50 MHz to 10 GHz. In addition, this thesis compares the eight designs’ insertion losses and discusses the possible relationship between particular structures of meandered lines and their corresponding frequency responses.Ope
