Satellite Antenna Gain Calculator

Dbi means relative to an isotropic omni directional antenna.

Satellite antenna gain calculator.

The eirp can take into account the losses in transmission line connectors and includes the gain of the antenna. Distance to from and round trip time delay calculator. 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. It is represented in db.

Beasley and gary m. This is a theoretical source that is used as the benchmark against which most antennas are compared. Parabolic antenna calculator example. Parabolic dish is widely used as satellite tv channel receiver across the world.

Antenna gain is the measure of amount of boost provided to the input sigal by the antenna. The above formula is to calculate the gain of a parabolic dish antenna where. 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. The uplink system noise temperature is obviously related to the quality of the receive low noise input amplifier on the satellite waveguides.

Lambda the wavelength of the antenna in meters. Gain 52 3 db beamwidth 0 35 degrees aperture 5 77 meter 2 parabolic antenna calculator equation. The results are increasingly approximate beyond the 3 db contour. K the efficiency fo the antenna.

Figure of merit calculator. The advanced beam forming enables efficient interference reduction toward the terrestrial fs systems by setting nulls at those directions 59. This has been calculated based on the frequency entered frequency to wavelength calculator. The parabolic reflector antenna gain is calculated as the gain over an isotropic source i e.

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. Satellite system calculator for modern electronic communication 9 e jeffrey s. Antenna gain dbi beamwidth aperture efficiency calculator. Antenna gain calculator example.

Frequency 14 5 ghz diameter 3 5 meter outputs. Azimuth and elevation calculator. The first null may appear at an angle off the boresight similar to the 3 db full beamwidth. Antenna efficiency 0 7 antenna diameter 4 2 meter antenna frequency 6 ghz output gain dbi 47.

Relative to a source that radiates equally in all directions. It is very useful in rf system link budget calculation and analysis. 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 calculator equation.
