Satellite Antenna Gain Calculator

K the efficiency fo the antenna.

Satellite antenna gain calculator.

Dbi means relative to an isotropic omni directional antenna. Beasley and gary m. Parabolic dish is widely used as satellite tv channel receiver across the world. The antenna gain shown in top line of the results is the on axis gain.

Figure of merit calculator. D the diameter of the dish. The uplink system noise temperature is obviously related to the quality of the receive low noise input amplifier on the satellite waveguides. This is a theoretical source that is used as the benchmark against which most antennas are compared.

Antenna gain is the measure of amount of boost provided to the input sigal by the antenna. The results are increasingly approximate beyond the 3 db contour. Parabolic antenna calculator example. The uplink antenna gain is easy to calculate.

Gain 52 3 db beamwidth 0 35 degrees aperture 5 77 meter 2 parabolic antenna calculator equation. If you are designing a satellite you may estimate the uplink g t by considering the uplink antenna gain and the satellite receive system noise temperature. The advanced beam forming enables efficient interference reduction toward the terrestrial fs systems by setting nulls at those directions 59. Eirp or effective isotropically radiated power or equivalent isotropically radiated power is a measurement of output power in one direction from an ideal one dimensional source the ideal point source radiates electromagnetic energy in a spherical pattern so the maximum radiated power should be the same in all directions.

Maximum main beam gain. Enter the transmitted power cable loss and antenna gain to calculate the eirp effective isotropic radiated power. It is the output power when a signal is concentrated into a smaller area by the antenna. Antenna gain dbi beamwidth aperture efficiency calculator.

It is very useful in rf system link budget calculation and analysis. Satellite system calculator for modern electronic communication 9 e jeffrey s. The above formula is to calculate the gain of a parabolic dish antenna where. Thus the fss terminal has large effective radiated power toward the fss satellite which is mainly due to its narrow beam high gain antenna e g 43 dbi antenna gain.

Antenna gain calculator example. Antenna gain calculator equation. Frequency 14 5 ghz diameter 3 5 meter outputs. Relative to a source that radiates equally in all directions.

Distance to from and round trip time delay calculator. Antenna efficiency 0 7 antenna diameter 4 2 meter antenna frequency 6 ghz output gain dbi 47. It is represented in db. Azimuth and elevation calculator.

This has been calculated based on the frequency entered frequency to wavelength calculator. Lambda the wavelength of the antenna in meters.
