Satellite Antenna Gain Calculator

It is the power supplied to an antenna multiplied by the antenna gain in a given.

Satellite antenna gain calculator.

Parabolic dish is widely used as satellite tv channel receiver across the world. Parabolic antenna calculator example. Finally click on the calculate button for the pure erp and eirp. 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. The above formula is to calculate the gain of a parabolic dish antenna where. There are two calculators here so you can compare the results against each other. 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 uplink antenna gain is easy to calculate. K the efficiency fo the antenna. Dbi means relative to an isotropic omni directional antenna.

Antenna gain calculator equation. Then enter the antenna gain. Antenna gain dbi beamwidth aperture efficiency calculator. The results are increasingly approximate beyond the 3 db contour.

The first null may appear at an angle off the boresight similar to the 3 db full beamwidth. Antenna gain calculator example. This analysis does not accomodate for power or gain in the system which you can easily overcome with antenna and rf amplifier size. By definition erp is the abbreviation for effective radiated power that is directed in a given direction.

Antenna gain is the measure of amount of boost provided to the input sigal by the antenna. Beasley and gary m. 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. This calculator is considering only power and antenna gain.

Satellite system calculator for modern electronic communication 9 e jeffrey s. It is very useful in rf system link budget calculation and analysis. Gain 52 3 db beamwidth 0 35 degrees aperture 5 77 meter 2 parabolic antenna calculator equation. D the diameter of the dish.

Antenna efficiency 0 7 antenna diameter 4 2 meter antenna frequency 6 ghz output gain dbi 47. Simply enter the efficiency wave length physical aperture area to calculate the gain or frequency of antennas. Distance to from and round trip time delay calculator. Frequency 14 5 ghz diameter 3 5 meter outputs.
