Evaluation of Radiated Emissions from Multi-port Integrated Connector Modules (ICM) by S-parameters

In this paper we present a systematic method to evaluate radiation of multi-port integrated connector modules (ICM) by S-parameters. A novel test jig is designed and built to measure S-parameters of two columns of ICM ports simultaneously. Based on radiation physics of ICM, a radiation model is created and an F factor to correlate S-parameters to far field radiation is defined. A good correlation is found between the F value and radiation from ICM ports.
