transition from connector to board

hellow
i want to use a connector like sma or smp that must be normal to my microstripline.
if for example i can use a ready connector for my project, like p-e-4-4-4-8-1;
the land pattern that was suitable at 4ghz, is different in compare to one's at 14ghz.
how can i guess the true land pattern?

and also what recomendations i must consider to elect my suitable commercial connector?

Any Idea Please...

thanks in advance
