In microwave circuit, the microstrip line has many problems one of these problems are crosstalk (coupling). Coupling is an important problem for the circuits that have multi-lines, which is induced by the difference between the capacitive coupling ratio (Cm=CT) and inductive coupling ratio. This problem is still very important due to the usage of the Very Large-Scale Integration. The study shows that the microstrip lines can be easily adapted to the small dimensions. The study aims to investigate the use of rectangular trace to reduce the crosstalk of the coupled microstrip lines. New electronic products must have high-speed, small size and lower voltages supply. With such layout, signal integrity (SI) becomes an actual important issue because sensitive equipment is affected on electromagnetic interference (EMI). Crosstalk is a major factor in signal integrity (SI) of printed circuit boards (PCBs). Crosstalk noise is usually represented in terms of Near-End crosstalk (NEXT) and FarEnd crosstalk (FEXT). Crosstalk is a common problem that degrades circuit performance. To reduce this problem, via hole-fences connected by guard trace between double microstrip lines are used, in this case the crosstalk will be reduce by 6 dB than use 3 W rule, but when it replaced by rectangular metal the crosstalk was reduce by 7 dB , is better than use via holefences by 1 dB . The simulation result was done by using FEKO 5.5 simulator. In conclusion, changing and reducing the crosstalk between double microstrip lines was compared to three techniques, using rectangular trace between microstrip lines new method compared it with the other two methods (3W rule and using via fence) all have the same dimensions.
