Satellite system calculator for modern electronic communication 9 e jeffrey s.
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 efficiency 0 7 antenna diameter 4 2 meter antenna frequency 6 ghz output gain dbi 47.
Gain 52 3 db beamwidth 0 35 degrees aperture 5 77 meter 2 parabolic antenna calculator equation.
The parabolic reflector antenna gain is calculated as the gain over an isotropic source i e.
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.
It is the output power when a signal is concentrated into a smaller area by the 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.
The antenna gain shown in top line of the results is the on axis gain.
It is represented in db.
The uplink system noise temperature is obviously related to the quality of the receive low noise input amplifier on the satellite waveguides.
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.
