Which limitation arises when signal propagation frequency increases?

A)Dielectric losses cause signal attenuation
B)Ohmic resistance assists lower impedance
C)Lower inductance enhances data transmission
D)Higher EM gain lowers signal reflections

💡 Explanation

Dielectric materials absorb energy propagating electromagnetic waves increases with rising frequency because dipole relaxation increases. Therefore, dielectric losses cause attenuation, rather than lower resistance assisting impedance, due to frequency influences.
