Formulas to find Total Input Power

Radiated Power

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.

Symbol: P_rad

Measurement: PowerUnit: W

Note: Value can be positive or negative.

Formulas to find Radiated Power

Antenna Efficiency

Antenna efficiency is the ratio of power radiated (Prad) by the antenna to the power supplied (Ps) to the antenna.

Symbol: E_t

Measurement: NAUnit: Unitless

Note: Value can be positive or negative.

How to Evaluate Total Input Power?

Total Input Power evaluator uses Total Input Power = Radiated Power/Antenna Efficiency to evaluate 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.

How to evaluate Total Input Power using this online evaluator? To use this online evaluator for Total Input Power, enter Radiated Power (P_rad) & Antenna Efficiency (E_t) and hit the calculate button.
