← ScienceWhich risk increases when parasitic capacitance couples resonant antenna stages?
A)Spurious electromagnetic wave emissions✓
B)Decreased antenna radiation resistance
C)Reduced antenna bandwidth efficiency
D)Increased feedline impedance matching
💡 Explanation
Spurious emissions increase with parasitic capacitance, because unwanted oscillations via capacitive coupling induce additional electromagnetic waves. Therefore, unintended frequencies radiate, rather than optimal transmitted signal frequencies; impedance mismatching impairs signal strength.
