The in-lab results relating to the fibre reinforced composites with different combination of the fibre reinforcements and the polymer matrix will be presented in this paper. We focus mainly on the electromagnetic emission signals (EMEs) when the sample is exposed to the axial compressive load. The detection system sensitivity issue is discussed, too. The capacitance sensor is used as a reference and excess noise signals are analysed in details. Our experimental results strongly indicate that the sample geometry and the contacts metallization can affect the detection limit significantly. The electric equivalent model including sample real properties is used here. As an alternative to capacitance sensor will be presented the near-field antenna probes reducing the metallization problems. Nevertheless, limitation given by less resistance to interfering signals and random changes in transmission conditions has been observed.
