In this article, a mode composite substrate integrated coaxial line (MCSICL) is proposed for transmitting fundamental mode and first high-order mode in dual frequency bands. The MCSICL consists of ...

In this work, a rigorous approach for the design of a differential coupled-line directional coupler (DCLDC) implemented in double-side coplanar-waveguide (CPW) technology is presented. Due to the ...
