Antenna Diameter (m): Antenna Gain (dB): Frequency (MHz): Antenna Efficiency (%): Antenna Efficiency calculator uses antenna_efficiency = radiation power / total input power to calculate the antenna efficiency, The Antenna Efficiency formula is defined as the ratio of power radiated (Prad) by the antenna to the power supplied (Ps) to the antenna. Antenna diameter (width): 0.97 m; Antenna diameter (height): 1.04 m; Antenna gain: 39.4 dB @ Frequency: 10950 MHz; Antenna efficiency: 65.67 %; The above calculation is only valid for offset or PFA dishes! How to calculate antenna gain? First, determine the efficiency. Measure the electrical efficiency of the antenna. Next, determine the wave length. Calculate the wave length of the waves produces by the antenna.

Antenna efficiency calculator

Normally provided by the antenna manufacturer and normally a value between 40 and 70 %. Frequency is chosen for the received signal in GHz. Example: 12,265 GHz. Effective aperture is represented as Ae and physical aperture is represented as Ap. For horn and reflector antennas, the aperture efficiency falls in the range of 50% to 80%. Use this Antenna aperture calculator to calculate antenna aperture efficiency at two different angles. Calculation of antenna efficiency.

Enter the diameter of your parabolic dish in m  The concept of antenna efficiency is introduced. Efficiency is a ratio of power supplied to the antenna to power radiated. The efficiency is always less than or  Another approach is to calculate the power lost in the structure and compare it to input power. This method is highly dependent on the structure and the surround-. Satellite Antenna Efficiency Calculator. Antenna Diameter, m. Antenna Gain, dB.

A — collecting area, Ae — effective aperture, E — electric field, H — magnetic field This calculator determines the effective aperture Ae for a given frequency f or wavelength, λ and antenna gain G. Antenna efficiency is also frequently quoted in decibels (dB) ; an efficiency of 0.1 is 10% or (-10 dB), and an efficiency of 0.5 or 50% is -3 dB. Equation is sometimes referred to as the antenna's radiation efficiency. This distinguishes it from another sometimes-used term, called an antenna's "total efficiency". Antenna Gain Calculator Equation Antenna Gain is the measure of amount of boost provided to the input sigal by the antenna. It is very useful in RF system link budget calculation and analysis. It helps to determine as to how much power we need to generate using RF Transmitter part bearing into consideration antenna gain information. This calculator determines the effective aperture A e for a given frequency f or wavelength, λ and antenna gain G.. Example: Calculate the effective antenna aperture of the Russian RT-70 radio telescope in Crimea (Russia): its antenna gain is 69.5 dBi or 9000000, working frequency 5.0 GHz (or wavelength 6 cm).

Next, determine the wave length. Calculate the wave length of the waves produces by the antenna. Next, determine the physical aperture area. Measure the total aperture area. Finally, calculate the antenna gain. The total efficiency of an antenna is the radiation efficiency multiplied by the impedance mismatch loss of the antenna, when connected to a transmission line or receiver (radio or transmitter). This can be summarized in Equation [2], where is the antenna's total efficiency, is the antenna's loss due to impedance mismatch, and is the antenna's radiation efficiency.
