Emission and immunity standards: replacing field-at-a-distance measurements with total-radiated-power measurements

This paper examines the use of total radiated power measurements, combined with theory-based directivity estimates, to generate accurate estimates for the maximum radiation and reception from a device. This approach may be a useful alternative to present test methods for emission and immunity as frequencies above 1GHz become necessary for EMC standards. Radiation-pattern data for theory-based estimates, Monte Carlo simulations of an arbitrary device, and measurements on a sample device are presented, and good data agreement is demonstrated.
