The aim of this paper is to study the different parts of a wireless system in order to better understand the signal properties and what key factors changes the signal during its transmission. Two transmitters were created, an FM transmitter that transmits analog data and an Arudino board programed to convert data to bits before its transmission. The acquired signals were then compared to the original signal noting how differently the data had changed. To understand the antennas contribution to the system a simulation was done using High Frequency Structural Simulator. A description of the analysis on the different acquired signals was done to determine the best applications they might have.
