← TechnologyWhich radio frequency (RF) interference outcome increases when antenna impedance mismatches occur?
A)Signal reflection and standing waves✓
B)Increased antenna radiation efficiency
C)Lower thermal noise figure
D)Improved impedance conjugate matching
💡 Explanation
Increased signal reflection and standing waves emerge because impedance mismatches cause a portion of the transmitted signal to bounce back to the source due to the impedance mismatch 'reflection coefficient'. This creates interference, therefore undesirable reflections appear, rather than desired wave propagation.
