Because low-loss transmission lines are desired to construct higher-performance circuits, a DTM line which consists of metal rod inserted into a dielectric tube and sandwiched by parallel metal plates has been proposed as a new transmission line. In the THz bands, the dimensions are so small that undesired air gaps between the parallel metal plates and the dielectric tube may occur, causing structural irregularities. The effect was analyzed for the air gap by calculating the normalized phase constant compared with that of the NRD guide which featured a low loss dielectric waveguide.
