Thelengthofthetraceorconnectionlineshouldbekeptasshortaspossible. Distance between connection and ground area on the top layer should at least be as large as the dielectric thickness. RoutingtheRFclosetodigitalsectionsofthesystemboardshouldbeavoided. To reduce signal reflections, sharp angles in the routing of the micro strip line should be avoided. Chamfers or fillets are preferred for rectangular routing; 45degree routing is preferred over Manhattan style 90degree routing.
