Satellite Antenna Gain Calculator

The uplink system noise temperature is obviously related to the quality of the receive low noise input amplifier on the satellite waveguides.

Satellite antenna gain calculator.

Frequency 14 5 ghz diameter 3 5 meter outputs. The first null may appear at an angle off the boresight similar to the 3 db full beamwidth. Relative to a source that radiates equally in all directions. It is very useful in rf system link budget calculation and analysis.

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. This is a theoretical source that is used as the benchmark against which most antennas are compared. Gain 52 3 db beamwidth 0 35 degrees aperture 5 77 meter 2 parabolic antenna calculator equation. 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.

Antenna gain dbi beamwidth aperture efficiency calculator. Parabolic dish is widely used as satellite tv channel receiver across the world. Lambda the wavelength of the antenna in meters. K the efficiency fo the antenna.

Antenna gain calculator example. Antenna gain is the measure of amount of boost provided to the input sigal by the antenna. The advanced beam forming enables efficient interference reduction toward the terrestrial fs systems by setting nulls at those directions 59. The uplink antenna gain is easy to calculate.

This has been calculated based on the frequency entered frequency to wavelength calculator. The eirp can take into account the losses in transmission line connectors and includes the gain of the antenna. It is represented in db. Antenna gain calculator equation.

Enter the transmitted power cable loss and antenna gain to calculate the eirp effective isotropic radiated power. Maximum main beam gain. D the diameter of the dish. The results are increasingly approximate beyond the 3 db contour.

It is the output power when a signal is concentrated into a smaller area by the antenna. Antenna efficiency 0 7 antenna diameter 4 2 meter antenna frequency 6 ghz output gain dbi 47. The above formula is to calculate the gain of a parabolic dish antenna where. Parabolic antenna calculator example.

Satellite system calculator for modern electronic communication 9 e jeffrey s. The antenna gain shown in top line of the results is the on axis gain. The parabolic reflector antenna gain is calculated as the gain over an isotropic source i e. Dbi means relative to an isotropic omni directional antenna.

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. Beasley and gary m.
