PCB선로의 끝단효과에 의한 특성임피던스 및 전자계분포에 관한 연구
A Study on Characteristic Impedance and Electromagnetic Distribution by the Edge Effect of Printed Cicuit Board Line
초록
Conventionally it is asummed that the microstrip line conductor has a rectangular cross-section. but the additive and substactive processes used to create conductors for PCBs produce a conductor of approximately Trapezoidal cross-section. For wide Strip line, the thickness and edge effect will be small since most of capacitance is parallel plate rather than fringing and we can ignore the cross-section. For narrow strip lines, the edge effect become immportant. So in this paper, we measure the chracteristic impedance of microstripline by Vector Analyzer and simulate the electromagnetic field of microstripline using finite element method with edge angle.
