← ScienceWhich outcome occurs when a radio antenna broadcasts near field?
A)Power dissipation becomes strongly distance-dependent✓
B)Far-field interferences are minimized effectively
C)EIRP calculations become standardized and reliable
D)Antenna gain becomes frequency independent locally
💡 Explanation
Excessive near-field propagation leads to rapid power dissipation, caused by reactive impedance rather than radiation resistance, because induced fields store energy locally near the antenna causing it to attenuate with distance; therefore power drops dramatically, rather than proper far field propagation.
