Abstract:
1. An electromagnetic interference suppressing device, comprising: a plurality of signal guiding units coupled to a metal housing of an electronic component for receiving a plurality of signals transmitted from the metal housing, wherein the electronic component is installed on a circuit board; a plurality of grounding units coupled to a plurality of ground pads of the circuit board for transmitting the plurality of signals to the plurality of ground pads; and a main body coupled to the plurality of signal guiding units and the plurality of grounding units for transmitting the plurality of signals between the plurality of signal guiding units and the plurality of grounding units so as to implement a return path; wherein power of electromagnetic interference corresponding to the plurality of signals is substantially less than 34 dB-microvolts per meter when frequency bands of the plurality of signals are between 30 megahertz and 224 megahertz and the power of electromagnetic interference corresponding to the plurality of signals is substantially less than 41 dB-microvolts per meter when the frequency bands of the plurality of signals are between 224 megahertz and 1 gigahertz.
