The antenna gain shown in top line of the results is the on axis gain.
Figure of merit calculator.
There are two calculators here so you can compare the results against each other.
Maximum main beam gain.
This calculator is considering only power and antenna gain.
D the diameter of the dish.
By definition erp is the abbreviation for effective radiated power that is directed in a given direction.
Then enter the antenna gain.
Dbi means relative to an isotropic omni directional antenna.
Lambda the wavelength of the antenna in meters.
The first null may appear at an angle off the boresight similar to the 3 db full beamwidth.
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.
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 results are increasingly approximate beyond the 3 db contour.
It is the power supplied to an antenna multiplied by the antenna gain in a given.
Antenna gain calculator example.
Simply enter the efficiency wave length physical aperture area to calculate the gain or frequency of antennas.
This has been calculated based on the frequency entered frequency to wavelength calculator.
