In dynamic systems modeling, this issues is known as causality.
In the case of inductances, one instantaneously asserts a voltage across the inductor and the inductive system then returns a time-varying value for the current. So, voltage is the input and current is the output. Note that it is impossible to instantaneously assert a current through an inductor, as this would require infinite voltage.
In the case of capacitances, one instantaneously asserts a current across the capacitor and the capacitive system then returns a time-varying value for the voltage, so, current is the input and voltage is the output in this case. Note that it is impossible to instantaneously assert a voltage across a capacitor as this would require infinite current.
In both cases, this is known as integral causality and is explained in detail in a treatment of power bond graphs.
In the case of a pure resistance, one can either assert a voltage as the input and obtain a current as the output, or assert a current as the input and obtain a voltage as the output.
For an antenna driven at resonance, the load is purely resistive, and current and voltage are related by ohm's law. If it is driven off-resonance, the load will possess either a capacitive or an inductive component and the above commentary applies.
