Problems solved by technology

All of the above interferences will affect the wireless transmission system, which will make it difficult for the wireless communication module to send and receive wireless signals. Therefore, it is necessary to suppress these interferences
[0005] Traditionally, common mode choke components are often installed on the circuit to suppress common mode noise. However, since the magnetic core with high magnetic permeability cannot effectively maintain high magnetic permeability in the high frequency band, on the contrary Shows the phenomenon of decay, which makes the common mode choke coil not suitable for common mode noise suppression under high-speed data transmission

Embodiment approach

[0076] exist Figure 4b Among them, the plan view patterns of the two defect grooves (1261a, 1263a) can be changed according to the needs. In various implementation modes, different electromagnetic interference (EMI) suppression effects can be achieved through the control of the geometric shape. According to The common-mode signal of a specific frequency range that needs to be suppressed through the differential pair signal transmission line (21, 22) is determined by the perimeter of the two defect slots (1261a, 1263a), that is, through the two defect slots The shape and size of (1261a, 1263a) can determine its circumference, and then can determine a part of the noise suppression ability.

[0077] In FIG. 4( c ), the conductive connection portion 132 is cylindrical as an example, and other shapes are applicable to the present invention, and are not limited to the shape in the drawing. In addition, the main function of the conductive connection part 132 is to connect the lead ...

Abstract

The invention discloses an electromagnetic interference suppressing structure and an electronic device having the same. Via disposing of a coplanar waveguide structure, a separation layer and a resonance layer, and under the coplanar waveguide structure, via connection of a conductive connection part in the separation layer and a conductor part of the resonance layer at the lower part, with such a stereoscopic structure, suppressing effect of electromagnetic interference is further improved, and better suppressing effect of electromagnetic interference is achieved.

Description

technical field [0001] The present invention relates to a structure for reducing electromagnetic interference and an electronic device using it, more particularly to a three-dimensional electromagnetic interference suppression structure using a coplanar waveguide (Co-Planar Waveguide, CPW) and a three-dimensional electromagnetic interference suppression structure with the Suppression structure of electronic devices. Background technique [0002] With the increasing popularity and development of various computer equipment, computer mainframes, handheld electronic devices, mobile communication equipment and other electronic equipment and devices that operate electronic systems, systems under electronic operation are inevitably subject to more and more external threats. Or internal electromagnetic interference (EMI), the source of which may be generated by other external electronic equipment or by other circuits within the electronic equipment itself. EMI suppression objects a...
