λ = (3 x 10^8 m/s) / (2.45 x 10^9 Hz) = 0.122 m

where S is the power density, P_t is the transmitted power, G is the antenna gain, and r is the distance from the antenna. λ = (3 x 10^8 m/s) / (2

Assuming a transmitted power of 1 W and an antenna gain of 10 dB (which is equivalent to a gain of 10), we get: S = (1 W * 10) / (4 * π * (100 m)^2) = 0

Problem 3: An antenna has a gain of 10 dB and is used to transmit a signal at a frequency of 1 GHz. What is the power density of the signal at a distance of 100 m from the antenna? P_t is the transmitted power

S = (1 W * 10) / (4 * π * (100 m)^2) = 0.079 W/m^2
