Abstract

In order to reduce far-end crosstalk between LTCC microstrip lines, this paper proposes a novel structure that has an air-cavity in dielectric layer. Simulation model of LTCC microstrip lines was set up by using Ansoft HFSS, the far-end crosstalk (S14) was obtained, the effects of cavity height, cavity width, location of cavity on far-end crosstalk strength between lines were studied. The results show that far-end crosstalk of proposed structure is reduced more than 12 dB from 18 GHz to 25.8 GHz compared with taking no any measures. The effect of reducing far-end crosstalk is nonlinear increasing with increasing of cavity width; the effect of reducing far-end crosstalk is increasing and then decreasing with increasing of cavity height. However, cavity height of the effect best is different in different frequency, in contrast, cavity height of the effect best is 0.14mm.When location of sample cavity in dielectric layer is different, the effect of reducing far-end crosstalk is different. Distance from bottom of cavity to ground plane of the effect best is 0.06mm.
