The real power radiated by short dipole is _____________ of the infinitesimal dipole.Select one:a. one-fourthb. one-thirdc. one-halfd. None of the above

To answer the question regarding the real power radiated by a short dipole compared to that of an infinitesimal dipole, we first need to understand the relationship between them.

1. Short Dipole vs. Infinitesimal Dipole:

   • An infinitesimal dipole is a theoretical concept where the length of the dipole approaches zero. In contrast, a short dipole (with finite length but still small compared to the wavelength) can be modeled to approximate the radiated power.

2. Radiated Power Comparison:

   • The power radiated by a short dipole is generally evaluated in terms of its effective length and the angle of radiation patterns. The factor by which the real power radiated by a short dipole differs from an infinitesimal dipole is well-established in electromagnetic theory.

3. Conclusion:

   • The short dipole radiates a power that is one-half of that radiated by an infinitesimal dipole under typical conditions. Hence, the answer to the multiple-choice question is c. one-half.

Final Answer

c. one-half
