A planar-type open-ended coaxial probe with substrate integrated waveguide structure has been developed for broadband permittivity measurement. The proposed probe consists of a microstrip line, a shielded stripline, and a coaxial aperture. The shielded stripline was formed by placing via-hole arrays along the stripline to form a substrate integrated waveguide. To access the bandwidth of the proposed...
This paper reports on a micromachined planar type probe based on a novel hybrid shielded stripline. The proposed structure is for a broadband transverse electromagnetic (TEM) single-mode propagation using substrate integrated waveguide (SIW) and conventional shielded stripline. We suggested a novel probe structure that composed of half-SIW and half-shielded stripline, which combined through a benzocyclobutene...
This paper reports a novel compact tunable composite right/left-handed transmission line (CRLH-TL) with multi-state phase tunability using integrated MEMS switches. It is possible to select multiple states with different positive/negative phase responses. The phase states can be determined by controlling the admittance of capacitors and impedance of inductors through MEMS switch operations. At 9.5...
