I know it sends radio signals but how does the transmiter creat the radio signals and the pattern, and what is the radio signal and what happens that makes the anttenna reacts and how the reciever knows when a radio signal is being recieved and what is it in the radio signal that gets reconized by the reciever and how it reconizes it.

Well this would take volumes, so I'll send you to previous answers to the same question. Just put "radio signal" or "Radio frequency" into the above box that is labeled "Search for Questions" (without the quotes) - or your favorite search engine. Wikipedia.com also has quite a large section on the subject.
