Subelement E9, ANTENNAS AND TRANSMISSION LINES· Group E9G
What type of coordinate system is used in a Smith chart?
- A.Voltage circles and current arcs
- B.Resistance circles and reactance arcs (correct answer)
- C.Voltage chords and current chords
- D.Resistance lines and reactance chords
WhyA Smith chart's coordinate system uses resistance circles and reactance arcs. A Smith chart's coordinate system is built from resistance circles and reactance arcs, two overlapping families of curves that together let any complex impedance be plotted as a single point, answer B. It isn't based on voltage circles and current arcs, voltage and current chords, or resistance lines paired with reactance chords, those don't describe the chart's actual resistance-circle-and-reactance-arc structure.
