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

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?

Solution: λ = c / f = (3 x 10^8 m/s) / (100 x 10^6 Hz) = 3 m [Page 2] λ = (3 x 10^8 m/s) / (2

λ = (3 x 10^8 m/s) / (100 x 10^6 Hz) = 3 m

The power density of the signal can be calculated using the formula:

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 [Page 3] Here

λ = c / f

[Page 3]

Here is a sample PDF version of the solution manual: λ = c / f S = (P_t * G) / (4 * π * r^2)

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.

The wavelength of a radio wave can be calculated using the formula:

Problem 2: A microwave oven uses a frequency of 2.45 GHz to heat food. What is the wavelength of this radiation?

λ = c / f

S = (P_t * G) / (4 * π * r^2)
