314MHz에서 작동하는 원격 무선 출입 시스템의 수신기 감도를 명확히 하려면 기내 안테나의 방사 특성을 연구해야 합니다. 이를 위해서는 전자기 시뮬레이션이 매우 유용하지만 객실에 존재하는 다중 반사파를 정확하게 추정해야 합니다. 기내 안테나의 방사 특성을 조사한 이전 연구는 없습니다. 본 논문에서는 정확한 시뮬레이션 방법을 소개합니다. MM(Method of Moments) 시뮬레이터는 여러 반사파를 시뮬레이션할 수 있기 때문에 선택되었습니다. 계산 요구 사항을 찾고 여러 반사파 구조의 수렴을 보장하기 위한 초기 연구가 수행되고 있습니다. 다음으로 융합변수, 컴퓨터 능력 등 자동차 분석을 위한 계산 요구사항을 연구한다. 계산 시간은 개인용 컴퓨터로 11시간입니다. 1.1GB RAM도 필요합니다. XNUMX차원 방사 패턴, 차체에 유도되는 전류 등 많은 계산 결과를 얻을 수 있습니다. 방사 패턴은 안테나 위치에 따라 달라지며 편파 변화도 표시됩니다. 결과의 정확성을 보장하기 위해 자동차의 XNUMX분의 XNUMX 크기 모델에서 측정이 이루어집니다. 측정된 결과와 계산된 결과가 잘 일치하면 시뮬레이션 방법의 타당성을 검증합니다. 다중 반사파가 방사 패턴에 미치는 영향도 실험적으로 연구되었습니다. 결론은 MM 방법이 기내 안테나의 방사 패턴을 추정하는 데 유용하다는 것입니다. 흥미로운 계산 결과도 표시됩니다.

Abstract: In order to clarify the receiver sensitivity of remote keyless entry systems operating at 314 MHz, the radiation characteristics of a cabin antennas must be studied. For this purpose, electromagnetic simulations are very useful but the multiple reflected waves present in the cabin must be accurately estimated. No prior study examined the radiation characteristics of cabin antennas. This paper introduces an accurate simulation method. A MM (Method of Moments) simulator is selected because it can simulate multiple reflected waves. Initial studies are being performed to find the calculation requirements and ensuring convergence of multiple reflected wave structures. Next, calculation requirements for car analyses such as convergence parameters and computer abilities are studied. The calculation time is 11 hours by a personal computer. 1.1 GB of RAM is also needed. Many calculated results such as three-dimensional radiation patterns and induced currents on the car's body are obtained. The radiation pattern varies with antenna position, and polarization changes are shown. In order to ensure that the results are accurate, measurements are made on a one seventh scale model of a car. The good agreement of measured and calculated results verifies the validity of the simulation method. The influence of multiple reflected waves on the radiation patterns is also experimentally studied. The conclusion is that the MM method is shown to be useful in estimating the radiation pattern of cabin antennas. Interesting calculation results are also shown.
