Towards Realistic Test Levels for Bulk Current Injection up to 6 GHz

摘要

Due to the increasing clock frequencies and decreasing rise times, the mandatory upper frequency limit for radiated emission and susceptibility testing on electronic modules are increasing up to 3 or even 6 GHz. The Bulk Current Injection test method has widely gained acceptance as alternative immunity test method. Unfortunately, test levels for this test method are only available up to 400 MHz. This paper addresses this issue by proposing a theoretical model based on antenna reciprocity that can be used to predict the worst-case current that is induced into a typical Bulk Current Injection set-up by an incoming plane wave.
