Measurements and Computations of Electric Field Intensity and Power Density

Conversion equations for converting the transmitting power, receiving power, or receiving voltage to electric field intensity and power density are derived and discussed. If the antenna factor, antenna gain, and the cable parameters are known, the electric field intensity or power density at some distance from the transmitting antenna may be determined by means of a specific conversion equation for a given signal frequency. The developed conversion equations may aid the electronics engineers to compute the electric field intensity and power density in a quick way.
