  • Patent number: 9250281
    Abstract: A method and a system for a handheld communication device is provided. The method includes: a testing a printed circuit board PCB assembly; identifying an emission point in the PCB; allocating a frequency radio (RF) absorber over or close to the emission point where the emission point is a potential source of electromagnetic interference (EMI) other than electronic components mounted on the PCB. The system includes a PCB assembly; and an RF absorber planar plate secured over or close to the emission point, for reducing the EMI from the emission point. A handheld communication device includes an antenna system and the PCB assembly with the RF absorber for isolating the antenna system from self-interference in the device.
