A shirt vertical grounded antenna is designed to radiate at 10 MHz. What will be radiation resistance of the antenna is the effective height of the antenna is 60 m?


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

N-->(1) R, =1607² h= Effective height of the antenna 2= Wavelength of radiation 2.

Step 3

In this case, the values of the effective height of the antenna and the frequency of radiation are given as...
