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.

Assuming a transmitted power of 1 W and an antenna gain of 10 dB (which is equivalent to a gain of 10), we get:

Solution: λ = c / f = (3 x 10^8 m/s) / (2.45 x 10^9 Hz) = 0.122 m where S is the power density, P_t is

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

A microwave oven uses a frequency of 2.45 GHz to heat food. What is the wavelength of this radiation? where λ is the wavelength, c is the

where λ is the wavelength, c is the speed of light (approximately 3 x 10^8 m/s), and f is the frequency.

λ = c / f

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?
