What is the space wave propagation frequency?
Space wave propagation frequency is nothing special, it is the same frequency of the wave in question, for example WLAN Wifi produces 5.2 GHz radio wave from your computer or from router, so that would be the the space wave propagation frequency in question
Which antenna is best excited by a wave guide?
Horn Antenna is best exited by waveguide
What is effective length of half wave dipole antenna?
The effective length of a half-wave dipole antenna is typically about half the wavelength of the frequency it is designed to operate at. This means the antenna's total length is approximately ( \frac{468}{f(MHz)} ) feet, where ( f ) is the frequency in megahertz. For example, at 100 MHz, the half-wave dipole would be about 4.68 feet long. This length allows the antenna to resonate efficiently, maximizing its radiation pattern and performance.
What is a list of the parameters that control the design of earth station?
The earth station depends on the following parameters• Transmitter power• Choice of frequency• Gain of antenna• Antenna efficiency• Antenna pointing accuracy• Noise temperature• Local conditions such as wind, weather etc,• Polarization• Propagation losses
Why do radio waves with extremely long wavelengths such as ELF radio waves need huge antennas?
Answer: An antenna is a tuned circuit, so it have to be tuned to the wavelength of the signal that it will transmit. If the antenna is not tuned properly some of the transmitted power will be feed back to the transmitter and will damage the output stage, SWR (Standing Wave Ratio) is very important, that is the ratio between the power that is transmitted by the antenna and the power that is fed back to the transmitter a zero is ideal but not always possible.The lower the frequency the longer the wave length and a 1/4 wave length is the minimum length that will give one a good SWR. The formula to use when one design a antenna is 300/frequency in MHz, if the frequency is 30 MHz then it is 300/30 = 10 Meter divide it by 4 to get the length of the 1/4 wave antenna that is 2,5 meters.Note: The antenna have to be multiples of a 1/4 wavelength like 1/2 wave or full wave, a 5/8 length can be used but it will need a L/C circuit at the input of the antenna to tune it to the frequency.
What are principal planes in antenna wave propagation?
The principal plane in wave propagation is the E-plane and the H-plane of an antenna. The E-plane consists of the electric field vector, and by convention, it's the direction in which the wave is said to be 'polarized'. The H-plane consists of magnetic field vector of the wave. The electric field vector and the magnetic field vector are perpendicular to each other, and the direction in which the wave propagates (moves) is perpendicular to both of them.
What is the different modes of the radio wave propagation?
Ground wave, sky wave and space wave propagation
What is the direction of wave propagation in a transverse wave?
In a transverse wave, the direction of wave propagation is perpendicular to the direction of the wave oscillation.
2 ray model of space wave propagation?
Loss = 120 + 40*log(d) - 20*log(h1) - 20*log(h2) d=distance between antenna in kilometersh1 and h2 are heights of antenna in meters.
What should be the position of the antenna with respect to the direction of the transmitted radio waves so that the properly tuned in radio gives the better reception?
The antenna should be parallel to the electrostatic field of the wave, and perpendicular to its magnetic field and to its direction of propagation.
What type of propagation is used in telephone communication?
Wave propagation
What is the relationship between the wavelength and the propagation direction in a longitudinal wave?
In a longitudinal wave, the wavelength is the distance between two consecutive points that are in phase with each other. The propagation direction of the wave is the direction in which the wave is moving. The relationship between the wavelength and the propagation direction in a longitudinal wave is that the wavelength is parallel to the propagation direction.
What is the direction of oscillation of the particles of each wave?
In a transverse wave, the particles oscillate perpendicular to the direction of wave propagation. In a longitudinal wave, the particles oscillate parallel to the direction of wave propagation.
What is the space wave propagation frequency?
Space wave propagation frequency is nothing special, it is the same frequency of the wave in question, for example WLAN Wifi produces 5.2 GHz radio wave from your computer or from router, so that would be the the space wave propagation frequency in question
End fire antenna?
end-fire antenna = surface-wave antenna
What is direction of a waves motion called?
Well, it's often referred to as the direction of propagation of the wave.
The speed at which the wave crests move is the?
... wave's speed of propagation.
