Simply enter the efficiency wave length physical aperture area to calculate the gain or frequency of antennas.
Satellite antenna gain calculator.
The antenna gain shown in top line of the results is the on axis gain.
There are two calculators here so you can compare the results against each other.
Maximum main beam gain.
Dbi means relative to an isotropic omni directional antenna.
Parabolic antenna calculator example.
By definition erp is the abbreviation for effective radiated power that is directed in a given direction.
Lambda the wavelength of the antenna in meters.
Satellite system calculator for modern electronic communication 9 e jeffrey s.
The first null may appear at an angle off the boresight similar to the 3 db full beamwidth.
This calculator is considering only power and antenna gain.
The above formula is to calculate the gain of a parabolic dish antenna where.
This has been calculated based on the frequency entered frequency to wavelength calculator.
This analysis does not accomodate for power or gain in the system which you can easily overcome with antenna and rf amplifier size.
D the diameter of the dish.
Then enter the antenna gain.
It is very useful in rf system link budget calculation and analysis.
The uplink antenna gain is easy to calculate.
Antenna gain calculator example.
Beasley and gary m.
Figure of merit calculator.
Finally click on the calculate button for the pure erp and eirp.
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 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.
Antenna efficiency 0 7 antenna diameter 4 2 meter antenna frequency 6 ghz output gain dbi 47.
Frequency 14 5 ghz diameter 3 5 meter outputs.
The results are increasingly approximate beyond the 3 db contour.
K the efficiency fo the antenna.
Antenna gain is the measure of amount of boost provided to the input sigal by the antenna.
Parabolic dish is widely used as satellite tv channel receiver across the world.
It is the power supplied to an antenna multiplied by the antenna gain in a given.
Antenna gain calculator equation.
The uplink system noise temperature is obviously related to the quality of the receive low noise input amplifier on the satellite waveguides.
Azimuth and elevation calculator.
