The tolerance of dielectric constant between raw material before the substrate production and real sample after the process variation is the kernel of this project. In the past, the electrical data sheet of dielectric material always comes from the suppliers. However, material suppliers do not consider the effect of substrate manufacture but only implement the measurement through raw materials. Therefore,...
In this paper, a new guided wave configuration hybrid integrated SIW-CPW with compact layout is proposed. The transmission performance, dispersion performance, attenuation performance and Sensitivities of characteristic of SIW-CPW with respect to various parameters are simulated. The results show that the SIW-CPW with the almost same normalized propagation constant and attenuation constant has lower...
A series of SrTiO3 (STO) based temperature compensation dielectrics that were cofireable with the commercial DuPont 951 low-temperature cofireable ceramic (LTCC) were developed. The STO30 dielectric with 30 wt% STO showed the highest positive temperature coefficient of resonant frequency (\(\tau _{f}\) ) that was opposite to the \(\tau _{f}=-69\) ppm/°C of the Dupont 951 LTCC, and was selected...
This paper presents the analysis of a microstrip line over a perfect magnetic conductor (PMC) ground plane. The electrostatic characteristics are at first investigated, then a full-wave analysis is performed.
