Satellite Antenna Gain Calculator

This calculator is considering only power and antenna gain.

Satellite antenna gain calculator.

Azimuth and elevation calculator. Antenna gain calculator example. 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.

Dbi means relative to an isotropic omni directional antenna. Antenna efficiency 0 7 antenna diameter 4 2 meter antenna frequency 6 ghz output gain dbi 47. Antenna gain dbi beamwidth aperture efficiency calculator. K the efficiency fo 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. Lambda the wavelength of the antenna in meters. It is very useful in rf system link budget calculation and analysis. 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. This has been calculated based on the frequency entered frequency to wavelength calculator. Finally click on the calculate button for the pure erp and eirp. Beasley and gary m.

It is the power supplied to an antenna multiplied by the antenna gain in a given. Parabolic dish is widely used as satellite tv channel receiver across the world. Parabolic antenna calculator example. The first null may appear at an angle off the boresight similar to the 3 db full beamwidth.

Then enter the antenna gain. The antenna gain shown in top line of the results is the on axis gain. 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. Satellite system calculator for modern electronic communication 9 e jeffrey s.

The uplink system noise temperature is obviously related to the quality of the receive low noise input amplifier on the satellite waveguides. The results are increasingly approximate beyond the 3 db contour. Figure of merit calculator. Antenna gain is the measure of amount of boost provided to the input sigal by the antenna.

The uplink antenna gain is easy to calculate. Maximum main beam gain. The above formula is to calculate the gain of a parabolic dish antenna where. Frequency 14 5 ghz diameter 3 5 meter outputs.

There are two calculators here so you can compare the results against each other.
