← ScienceWhich outcome occurs when a microstrip antenna conductor narrows?
A)Reactive impedance increases drastically✓
B)Radiated power increases linearly
C)Conduction losses decrease sharply
D)Bandwidth broadens significantly
💡 Explanation
Reactive impedance increases because the *current crowding effect* raises inductance at the constriction, therefore the antenna impedance departs significantly from its designed value, rather than enhancing radiation or bandwidth, which require impedance matching.
