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?
Electromagnetic waves are a fundamental part of the electromagnetic spectrum, which includes all types of electromagnetic radiation, from low-frequency waves like radio waves to high-frequency waves like gamma rays. Radiating systems, on the other hand, are systems that generate and transmit electromagnetic waves. Problem 3: An antenna has a gain of
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? Radiating systems, on the other hand, are systems
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. where S is the power density, P_t is
λ = (3 x 10^8 m/s) / (2.45 x 10^9 Hz) = 0.122 m
What is the wavelength of a radio wave with a frequency of 100 MHz?
