Answer 3

Standing Wave

Question 4

Points of zero amplitude

Answer 4

Nodes

Question 5

Points of maximum amplitude

Answer 5

Antinodes

Question 6

The ratio of reflected power to incident power in a waveguide

Answer 6

Power Reflection Coefficient

Question 7

Ratio of reflected voltage to incident voltage in a transmission line

Answer 7

Reflection Coefficient (Γ)

Question 8

Expressed in dB, it is the negative of the power reflection coefficient in dB.

Answer 8

Return Loss

Question 9

Measure of mismatch; indicates how much signal is reflected back.

Answer 9

VSWR (Voltage Standing Wave Ratio)

Question 10

Opposition to current flow in a circuit; expressed as a complex number 𝑍=𝑅+𝑗𝑋

Answer 10

Impedance (Z)

Question 11

Reciprocal of impedance;
Y=G+jB, where G is conductance and B is susceptance

Answer 11

Admittance (Y)

Question 12

used to generalize Smith chart plots.

Answer 12

Normalized Impedance (Zn)

Question 13

Combines impedance and admittance charts for complex analysis.

Answer 13

Immittance Chart (YZ chart)

Question 14

Located far left on Smith chart; complete reflection with 180° phase shift.

Answer 14

Short Circuit (ZL = 0)

Question 15

Located far right; complete reflection with no phase shift.

Answer 15

Open Circuit (ZL = ∞)

Question 16

Center of the chart; no reflection.

Answer 16

Matched Load (ZL = Z0)
