Expert Answer

Step 1

Radiation resistance is a fictitious resistance. When an antenna radiates, the total power radiated by the antenna is assumed to the equal to the power dissipated by a specific resistance. That specific resistance is the radiation resistance of an antenna.

Step 2

For a short vertical grounded antenna, the radiation resistance can be expressed as
