At a distance of 10 m from a transmitting antenna, the maximum radiated power is measured as 160 microW/cm². If the transmitting antenna is radiating 120 W power, then determine the gain of the transmitting antenna.

Expert Solution

Step 1

If P_T is the power emitted by the transmitting antenna having a gain of G_T, then the power density P_d at a distance d away from the transmitting antenna can be expressed as

Step 2

In this case, the values of the power transmitted by the antenna, the distance at which the power density is provided and the distance from the transmitting antenna are given as
