Satellite Antenna Gain Calculator

The results are increasingly approximate beyond the 3 db contour.

Satellite antenna gain calculator.

Antenna efficiency 0 7 antenna diameter 4 2 meter antenna frequency 6 ghz output gain dbi 47. Dbi means relative to an isotropic omni directional antenna. 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. Gain 52 3 db beamwidth 0 35 degrees aperture 5 77 meter 2 parabolic antenna calculator equation.

Distance to from and round trip time delay calculator. Figure of merit calculator. Parabolic dish is widely used as satellite tv channel receiver across the world. It is represented in db.

This has been calculated based on the frequency entered frequency to wavelength calculator. It is the output power when a signal is concentrated into a smaller area by the antenna. K the efficiency fo the antenna. Antenna gain calculator equation.

Relative to a source that radiates equally in all directions. The parabolic reflector antenna gain is calculated as the gain over an isotropic source i e. The eirp can take into account the losses in transmission line connectors and includes the gain of the antenna. 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.

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 first null may appear at an angle off the boresight similar to the 3 db full beamwidth. Frequency 14 5 ghz diameter 3 5 meter outputs. The uplink antenna gain is easy to calculate.

Antenna gain is the measure of amount of boost provided to the input sigal by the antenna. Antenna gain calculator example. Antenna gain dbi beamwidth aperture efficiency calculator. This is a theoretical source that is used as the benchmark against which most antennas are compared.

Parabolic antenna calculator example. Enter the transmitted power cable loss and antenna gain to calculate the eirp effective isotropic radiated power. Beasley and gary m. Maximum main beam gain.

The antenna gain shown in top line of the results is the on axis gain. It is very useful in rf system link budget calculation and analysis. D the diameter of the dish. Lambda the wavelength of the antenna in meters.

The advanced beam forming enables efficient interference reduction toward the terrestrial fs systems by setting nulls at those directions 59. Satellite system calculator for modern electronic communication 9 e jeffrey s.
