On Radiated Susceptibility Testing of Highly Directive Devices

Radiated susceptibility testing of a highly directive device is challenging. To ensure the worst case coupling test in an anechoic chamber, an exhaustive measurement scheme is required which usually is not a viable option. When a test is performed with minimal requirements, the potential to miss susceptibilities are high and the uncertainty worsens when directivity is a function of frequency. Reverberation chambers assure best case susceptibility tests due to the nature of complex cavities but the potential to under test is also present as the directivity of the EUT are smoothed out. In this study, simulations are performed on a box with apertures to calculate directivity. An anechoic chamber test and reverb like tests are simulated to calculate the coupling. The differences in maximums of the induced fields are shown as a comparison.
