Abstract

In recent years, mobile devices have become increasingly multi-functional and high performance, resulting in a dramatical increase in processing speed. On the other hand, the size of device is reduced, circuits inside the device are more easily exposed to electromagnetic interference radiated from antenna or adjacent circuits, degrading the system performance. To prevent this, it is necessary to design the device considering the electromagnetic characteristics with EM simulation at the design stage of product. However, the EM simulation takes a long analysis time and require high-level system resources for fast analysis. In this paper, an equivalent circuit modeling method for a round wire is proposed using a PEEC method and the electromagnetic coupling from a dipole antenna to a transmission line is analyzed in frequency domain. And compared with the result of electromagnetic simulator. As a result, PEEC method shows good agreement with those of electromagnetic simulation, in a much more short time.

최근 모바일 기기는 다기능, 고성능화로 정보 처리 속도는 빠르게 증가하고, 제품의 크기는 소형화, 집적화되면서 기기 내부의 회로는 안테나 또는 인접 회로로부터 방사되는 전자기 간섭에 쉽게 노출되게 되었고, 제품의 성능 저하 및 오동작을 유발시킨다. 이를 방지하기 위해 제품의 설계 단계에서 EM 시뮬레이션을 통해 제품의 전자기적 특성을 예측하고, 이를 고려하여 설계해야 하지만, EM 시뮬레이터는 분석 시간이 오래 걸리고, 분석시간을 단축시키기 위해서 고사양의 시스템 자원이 필요하다. 본 논문에서는 PEEC 방법을 이용하여 원형 전선에 대한 전자기적 특성을 빠르게 분석하는 방법을 제시하였다. PEEC 방법은 도체 내부의 전계 적분 방정식으로부터 도체의 등가회로를 모델링하고, 회로 분석법을 통해 전자기적 특성을 분석할 수 있는 방법으로, EM 시뮬레이터 대비 빠른 시간 안에 전자기적 특성을 분석할 수 있다. 본 논문에서 제시한 방법을 통해 다이폴 안테나로부터 전송선로로의 전자기 결합을 주파수 영역에서 분석하였고, 이를 EM 시뮬레이터의 분석 결과와 비교해 PEEC 방법의 유효함을 검증하였다.
