금속 메쉬 면을 포함한 함체에 대한 1-포트 품질계수 도출 방법.

This study was conducted to derive a quality factor for the evaluation of an enclosure with a metallic wire mesh. The electrical characteristics of the metal mesh surface can be determined through equivalent surface impedance conversion; thus, an enclosure was manufactured after analyzing the scattering parameters of the metallic wire mesh surface. The quality factor of the enclosure can be derived simply by measuring a single standard antenna bonded by 1-port. To verify the effectiveness of the 1-port time domain quality factor derivation method, a numerical simulation was performed using the Finite Integration Technique (FIT) of commercially available software CST Microwave Studio. The verified quality-factor derivation method was applied to an enclosure with a metallic wire mesh surface. A quality factor measurement experiment was performed for the case in which one side of the enclosure was in the opening surface, one side of the enclosure was a metallic wire mesh surface, and all the surfaces of the enclosure were closed with metal. Based on the measurements, the quality factor in the case of Open was the lowest at 26.82 dB, followed by 32.24 dB for the case of Mesh and 32.51 dB for the case of Closed. [ABSTRACT FROM AUTHOR]
