Abstract :
In this paper, different approaches to calculate the characteristic impedance of slotlines by finite difference time domain (FDTD) method is presented. It shows that for non-TEM mode transmission lines, different definitions of Z0 yield completely different results. Then a more rational definition of characteristic impedance of slotlines is proposed. Result is obtained and compared with other definitions.
