Abstract
In this paper, analysis and measurement on coaxial connecter designed for packaging of microwave and micro strip transition structure are carried out. Even though researches on optimization of various kinds of transition structures have been conducted actively; however, the range of the application was very limited since they have been focused mainly on improvement of specific transmission line. Therefore, in this paper, we tried to analyze three kinds of substrates of which dielectric constants are 2,5,10 and are commercially used nowadays. Besides, we have confirmed reliability of FEM analysis, extracted equivalent circuit of transition area, found out factors determining extracted physical values, and made proof of electromagnetic variations for optimum characteristics. In addition, transition structure showing optimized characteristics on the basis of dielectric and microstrip structure was proposed. We reckon that the result of this research will apply with effect to transition design in microwave packaging development.
