SUMMARYInterfaces between a coaxial structure and a post-wall waveguide are proposed as the essential components for cost-effective millimeter-wave modules. PTFE substrate is selected in terms of loss and manufacturability. The reflection and the transmission characteristics are investigated. The short-stepped and the short-taper-stepped feeding structures provide 14.7% and 13.2% bandwidths for the reflection smaller than −15 dB, respectively. The 46 × 40 mm 2 size antenna fed by the shortstepped structure in PTFE substrate gives 27.3 dBi with 58.2% efficiency at 60.0 GHz. Feeding structures in PTFE substrate fulfill electrical and manufacturing demands in millimeter-wave bands. key words: home-link system, coaxial, post-wall waveguide, millimeterwave band, PTFE

Abstract-A tunable planar bandpass filter based on a technique that utilizes a half mode substrate integrated waveguide (HMSIW) and novel inter-resonator coupling is presented. The tunable HMSIW based bandpass filter is implemented using two half triangle shaped cavities coupled together through inter-resonator coupling forming half mode bowtie shaped structure. The bowtie-shaped filter exhibits similar performance as found in rectangle-and circle-shaped SIW based bandpass filters. This concept reduces the circuit foot print, and miniaturization high quality factor is maintained by the structure. The tunable filter utilizes packaged RF MEMS switches; switching between different configurations of switches achieves four distinctive frequency states between 4.8-5.3 GHz. The filter maintains a constant absolute 1 dB bandwidth of 100 ± 10 MHz for all frequency states.

In this article, the concept of artificial transmission lines is introduced. These structures are transmission lines loaded with reactive elements. Thanks to the presence of these reactive elements, the lines can be engineered, and microwave devices with compact size, with superior performance, or with novel functionalities (as compared with those based on conventional lines), can be designed and fabricated. The article is mainly focused on slow‐wave artificial transmission lines and metamaterial‐based transmission lines. The circuit models of the lines, useful for design purposes, and the main physical implementations are reported. Finally, some applications of these artificial lines are highlighted, including device miniaturization, spurious suppression, multiband and broadband components, filters and diplexers, antennas, and sensors.
