Summary: 
This paper describes a dielectric phase shifter (DPS) using contact-less connector. As the main feature of this structure, an array of difference length strip conductor etched on a dielectric substrate placed on the microstrip patch resonators gives tightly coupling between input and output port. A sliding dielectric substrate provides phase shift for between input and output port. In this paper, the characteristics of DPS are calculated by finite difference time domain (FDTD) method, and are verified by experiments.
