1.	Power density of the receiving antenna is given by _________(a) \(P_D=\frac{P_t G_t}{4πd^2}\)(b) \(P_D=\frac{P_t G_t}{(4πd/λ)^2}\)(c) \(P_D=\frac{P_t G_t G_r}{(4πd/λ)^2}\)(d) \(P_D=\frac{P_t G_t}{(4πd)^2}\)I had been asked this question by my college director while I was bunking the class.This question is from Radio Wave Propagation in section Radio Wave Propagation of Antennas
Answer» The correct answer is (a) \(P_D=\frac{P_t G_t}{4πd^2}\) To ELABORATE: Power density is the power per unit AREA at a distance d from the transmitter and is GIVEN by \(P_D=\frac{P_t G_t}{4πd^2}\) where Pt is the transmitter power and Gt is the transmitter ANTENNA gain. Power received by the antenna is given by \(P_r=\frac{P_t G_t G_r}{(4πd/λ)^2}\)
