Vedclass · Answer

(C) An antenna is a transducer that converts electrical signals into electromagnetic waves (in transmission) or electromagnetic waves into electrical signals (in reception). It is not inherently just 'inductive' or 'capacitive' in a general sense,as its impedance depends on its design,length,and the operating frequency. At its resonant frequency,an antenna acts as a purely resistive load,meaning its impedance is real and contains no reactive component. Therefore,the most accurate description among the choices provided regarding its behavior at resonance is that it exhibits a specific impedance at its resonant frequency.
