Parabolic dish is widely used as satellite tv channel receiver across the world.
Satellite antenna gain calculator.
Maximum main beam gain.
Azimuth and elevation calculator.
This has been calculated based on the frequency entered frequency to wavelength calculator.
The uplink system noise temperature is obviously related to the quality of the receive low noise input amplifier on the satellite waveguides.
The above formula is to calculate the gain of a parabolic dish antenna where.
D the diameter of the dish.
Antenna efficiency 0 7 antenna diameter 4 2 meter antenna frequency 6 ghz output gain dbi 47.
Antenna gain calculator equation.
Beasley and gary m.
Antenna gain is the measure of amount of boost provided to the input sigal 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.
Simply enter the efficiency wave length physical aperture area to calculate the gain or frequency of antennas.
The antenna gain shown in top line of the results is the on axis gain.

Finally click on the calculate button for the pure erp and eirp.
Figure of merit calculator.
Then enter the antenna gain.
K the efficiency fo the antenna.
Distance to from and round trip time delay calculator.
Gain 52 3 db beamwidth 0 35 degrees aperture 5 77 meter 2 parabolic antenna calculator equation.
The first null may appear at an angle off the boresight similar to the 3 db full beamwidth.
The uplink antenna gain is easy to calculate.
Parabolic antenna calculator example.
This calculator is considering only power and antenna gain.
Dbi means relative to an isotropic omni directional antenna.
By definition erp is the abbreviation for effective radiated power that is directed in a given direction.
Frequency 14 5 ghz diameter 3 5 meter outputs.
Antenna gain dbi beamwidth aperture efficiency calculator.
The results are increasingly approximate beyond the 3 db contour.
The gain of an antenna dbi in a given direction is the amount of energy radiated in that direction compared to the energy an isotropic antenna would radiate in the same direction when driven with the same input power.
This analysis does not accomodate for power or gain in the system which you can easily overcome with antenna and rf amplifier size.
Lambda the wavelength of the antenna in meters.
