ISO11451-5 was published in May 2023 as a vehicle immunity test standard limited to reverberation chambers. In this study, we have designed a new parallel-plate Transverse Electromagnetic (TEM) antenna compliant with a Transmission Line System (TLS) described in Annex E as an immunity test method from 10 kHz to Lowest Useable Frequency (LUF), a fabricated 1/4 scale reverberation chamber, evaluated electric field uniformity, and ascertained its effectiveness. Further, using a 1/4 vehicle scale model, we have compared this immunity test method using a parallel-plate TEM antenna with the conventional immunity test methods using a TLS and a biconical antenna at an Absorber Lined Shielded Enclosure (ALSE) to ascertain its effectiveness.
