Microstrip Lines for Microwave Integrated Circuits

摘要: Microstrips, transmission lines of metallic layers deposited on a dielectric substrate, are very useful for the microwave and millimeter wave hybrid integrated circuits required solid-state radio systems because their simplicity planar structure. To design with microstrips requires computation or measurement impedance, attenuation, guide wavelength, unloaded Q line. These parameters can be obtained from effective constant characteristic impedance corresponding air This paper gives exact data all line most important cases. We report attenuation measurements performed microstrips. Satisfactory agreement is theoretical results based conformal mapping logarithmic derivatives theta functions expressions involving partial respect to independent parameters.
