Detection of paper sheets based on variation of antenna resonance characteristics

Detection of paper sheets based on variation of antenna resonance characteristics

This paper discusses the detection of the presence of paper inserted between the metal and the antenna. In order to clarify the feasibility of the sensing technique, we analyzed change of frequency characteristics of return loss in the presence or absence of paper near the antenna. Numerical analysi...

description This paper discusses the detection of the presence of paper inserted between the metal and the antenna. In order to clarify the feasibility of the sensing technique, we analyzed change of frequency characteristics of return loss in the presence or absence of paper near the antenna. Numerical analysis using the FDTD method was performed and experiments were carried out to compare the calculated and measured results. By the results, we confirmed detectable amount of change can be observed.
