← TechnologyWhich outcome acutely arises when impedance mismatch occurs in a parabolic dish antenna?
A)Signal power reflection increases sharply✓
B)Beamwidth broadens in the radiation pattern
C)Antenna gain improves dramatically always
D)Polarization purity becomes noticeably higher
💡 Explanation
Increased signal reflection is a result of impedance mismatch; this is because the reflected power uses Standing Wave Ratio (SWR) causing energy to bounce back toward the source, therefore less power radiates outwardly, rather than propagating energy efficiently and consistently to the intended distant receiver.
