Abstract

This paper investigates the emission of fields and field attenuation rates from electrically small transmitting loop antennas in the presence of a general half-space. Considerations are made for the practical effects of antenna loop dimension and source-to-sensor impedance coupling. The resulting field attenuation rates correlate well with open area test site (OATS) measurements. The tables provided may be readily used to extrapolate measured low-frequency emissions to common regulatory limit locations.
