摘要: Voltage and current cannot be defined uniquely for microstrip except at zero frequency, therefore has not been rigorously incorporated into circuit theory. However, in engineering practice, micro-strip exhibits an apparent characteristic impedance, denoted here by ZA, that can measured. Three methods of measuring ZA were devised used three impedance levels microstrip. These are described experimental results presented. The measurements found to consistent with the power-current definition approximate longitudinal-section electric (LSE) model nricrostrip. Simple formulas representing also discussed.
