  • The crosstalk of T-shaped microstrip is the important component in signal integrity of a high-speed circuit. In this paper, the fullwave analysis of the crosstalk is carried out by adopting the Perfectly Matched Layer Finite-Difference Time-Domain (PML-FDTD) method, and then the measures of reducing crosstalk are proposed in detail. The different structure parameters of improved T-shaped microstrip have different influence on the crosstalk. That is, (1) the crosstalk between microstrips is smaller as the orifice distance S is becoming bigger, and the amplitude of crosstalk is reduced to 10dB; (2) The value of is smaller as the crosstalk between microstrip is becoming smaller correspondingly, and the amplitude of crosstalk is reduced to 14dB. Thus opening an orifice on the T-shaped microstrip can reduce the crosstalk between one T-shaped microstrip and another adjacent one remarkably by changing orifice distance S and angle .
