Formula Used

Total Input Power = Radiated Power/Antenna Efficiency
P_i = P_rad/E_t
This formula uses 3 Variables

Variables Used

Total Input Power - (Measured in Watt) - Total input power is calculated by multiplying voltage (in volts) by current (in amps).
Radiated Power - (Measured in Watt) - Radiated Power is defined as power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity.
Antenna Efficiency - Antenna efficiency is the ratio of power radiated (Prad) by the antenna to the power supplied (Ps) to the antenna.

STEP 1: Convert Input(s) to Base Unit

What is total input current?

Input current is the amount of current drawn by the regulator in a regulated devices from the batteries needed to provide the output power selected by the user. This number is important because it tells us what kind of batteries we need to use for our devices to power them safely.

How to Calculate Total Input Power?

Total Input Power calculator uses Total Input Power = Radiated Power/Antenna Efficiency to calculate the Total Input Power, The Total Input Power formula is defined as is less than or equal to the input power, Pin, supplied at the input of the antenna. A part of the input power, Ploss, is dissipated as heat in the material (conductor or dielectric) of the antenna itself. Total Input Power is denoted by P_i symbol.
