Look for things like discontinuous impedance points, acute angles, etc. When the wire’s corner forms a straight angle or even an acute angle for high-frequency current, the magnetic flux density and electric field strength are comparatively high nearby, and the radiation will be stronger. The inductive reactance will be greater than the obtuse or rounded corners, and the electromagnetic wave and inductance will both be quite large. The corners of the wiring for the bus wiring of digital circuits have obtuse or rounded edges, and the wiring itself takes up a little amount of space. The overall line spacing takes up 0.3 times less space than the width of the right-angle corner when the same line spacing is used.
