“…respectively used the segmentation approach [7] [8] and viable wide-band circuit model [9] methods to analyze NUTL. Cai et al added graphene paraffin material to the signal line with labels to suppress FEXT [10] and increased the cost of batch production. Ma et al proposed a kind of guard trace based on a subwavelength periodic structure to reduce the FEXT of parallel microstrip lines [11] and limit the high-density layout.…”

High-speed and high-density PCB circuit layout design faces serious signal integrity problems. Crosstalk is one of the key problems affecting signal quality. Periodic non-uniform differential microstrip lines have the possibility of reducing crosstalk. This paper proposes a T-shaped non-uniform microstrip line, which adds the T-shaped bump on the inner side of the parallel microstrip lines. The microstrip line adopts the minimum batch production process linewidth to maintain high density, which is suitable for occasions where the line spacing is three times the linewidth. The principle of crosstalk mitigation for T-shaped microstrip lines is explained, and the evolution process of T-shaped microstrip lines is given, compared with parallel microstrip lines and tabbed lines with the same density. The simulation resulting in the time domain and frequency domain shows that the transmission performance of the T-shaped microstrip line is good, and crosstalk can be effectively suppressed in a high-frequency band, even better in some specific frequencies due to the crosstalk fluctuation with frequency.

“…Commonly used methods to reduce crosstalk are placing via fences [12], guard traces [13], serpentine guard traces [14], stubs [15], or resonators [16] between the two signal lines. Recently, a method of coating signal lines with graphene-paraffin has also been studied [17]. In most of the approaches, efforts are made to decrease the crosstalk levels by inserting additional structures between the conventional transmission lines.…”

A Novel Meander Split Power/Ground Plane Reducing Crosstalk of Traces Crossing Over

In this paper, a novel meander split power/ground plane is proposed for reducing crosstalk between parallel lines crossing over it. The working mechanism of the meander split scheme is investigated by simulations and measurements. The LC equivalent circuit and transmission line model are developed for modeling interactions between the meander split and the signal lines. The proposed meander structure enhances electromagnetic coupling between split planes. The capacitive coupling across the split ensures signal integrity and magnetic coupling between adjacent finger shaped structures suppresses lateral wave propagation along the split gap, which in turn helps suppress the crosstalk. The effectiveness of the meander split remains valid over very wide frequency ranges (up to 9 GHz). Experimental results show that the proposed structure improves the signal quality and reduces the near/far end crosstalk over 30 dB and 50% in the frequency domain and time domain, respectively.
