← ScienceWhich outcome occurs when parasitic capacitance changes unexpectedly within microstrip antennae?
A)Decreased impedance-matching bandwidth to source✓
B)Increased antennae transmission power output
C)Consistent antennae polarisation maintenance occurs
D)Predictable far-field radiation pattern increases
💡 Explanation
Decreased impedance-matching bandwidth occurs because the **capacitive reactance** shifts the resonance frequency, therefore the antenna misinputs waves because impedance mismatching creates reflected power to the transmitter rather than efficient bandwidth for transmission.
