Abstract
Substrate integrated coaxial line (SICL) has been widely used for high frequency interconnects. In this paper, a ridged substrate integrated coaxial line (RSICL) is proposed. It has similar structure to the SICL but has two ridges on both sides of the inner conductor. The proposed RSICL is a quasi-shielding structure which can support the transverse electromagnetic (TEM) mode. Moreover, the introduction of ridges into SICL can significantly minimize the interconnect size. The dominant mode and higher-order modes, the characteristic impedance and the propagation constants of the RSICL are analyzed based on the full-wave simulation software. Compared with the SICL, the RSICL can reduce the width of the internal and external conductors by 22.5% and 10%, respectively. Besides, the dominant mode bandwidth of the RSICL is 11 % wider than that of the SICL.
