help on design an microstip antenna array

hey i need to simulate an antenna array on cst i looked for tutorial but couldnt find them (and there are no usful tutorial in the program folder...) i need a tutorial that will explain the feed system (coax microstip,,,)

anybody ?

what exactly is your question? what does the feed system have to do with a tutorial for CST? there is plenty of literature describing how arrays are typically fed. i suggest searching here or the internet for 'corporate feeding antenna array' or something similar
