摘要：

Radiation from a complicated connector in the gigahertz range is investigated in this paper. In order to understand the radiation physics of the complex commercial connector, three simplified connector models were built. Simplified structure I was established to understand how the multiple wafers affect the radiation. It is discovered that the produced slot-like antenna structures between wafers can introducemore radiation peaks. For simplified structure II and simplified structure III, they were built to investigate the radiation performances from orphaned differential pair and typical differential pair. It is suggested that additional ground blade for the orphaned differential pair should be introduced to have lower radiation level. Finally, radiations from the typical differential pair for single wafer and multiple wafers are measured. The radiation peaks due to new slot-like antenna structures are observed. The radiations from the orphaned differential pair and typical differential are also measured and compared. Worse radiated emission for the orphaned differential pair within the commercial connector is given and is suggested not to use. Finally, a radiation mitigation method for the high-speed connector is also proposed.
