How to design low range of RF Tx and Rx (less than 100cm)

Perhaps many years - focused coursework - and then - thorough search/find/read/review of pertinent, industry literature.    (unlikely, here!)

Your "short distance" (100cm) suggests usage with toy/model emergency vehicles - to "prove concept."   (100 meters makes more sense - real-world)

RF operated "door-chimes" and/or "garage-door openers" enable such (likely), "RF, Study-Lite" solutions...   There's substantial difference between "design" and far simpler, "Application of existing technology/systems!"    That said - fortunes have been earned thru clever application of existing products and/or methods - real "design" not required...

 Hi CB1, I see forum level is just dropped a lot more to all asking have job done for free....

Beware Roberto - watch for, "uncleared, automatic, traffic emergency vehicle" speeding (did we say, "uncleared") into your path!
