← ScienceWhich consequence results when near-field communication antenna mismatch increases impedance?
A)Radio frequency impedance signal reflection✓
B)Increased magnetic field zone induction
C)Improved power wave attenuation stability
D)Faraday cage radiative field emission
💡 Explanation
Increased antenna impedance mismatch causes signal reflection because impedance differences impede efficient energy transfer. This activates standing waves. Reflection reduces power transmission, therefore it’s correct rather than improved wave attenuation, which would only occur under matched conditions.
