The intensity of radiation of a dipole depends strongly on frequency. If at a frequency f, the intensity of radiation is '$$I$$' then at a frequency of $$\frac{{\text{f}}}{2}$$, the intensity will be:

A. Radar B. Direction finding C. Satellite communication D. All of the above

A. Scalar B. Vector C. Unit vector D. None of the above

A. Hertz antenna B. Marconi antenna C. Folded dipole D. None of the above

A. Accelerating B. Retardation C. Oscillating D. Lagging the current
