TL;DR: In this paper, an approximate analysis of a slotted substrate integrated waveguide with periodic loading elements using the transverse resonance technique is provided, where pin diodes are capacitively coupled to the waveguide slot.
Abstract: This letter provides an approximate analysis of a slotted substrate integrated waveguide with periodic loading elements using the transverse resonance technique. The technique is used to design a travelling wave attenuator whereby pin diodes are capacitively coupled to the waveguide slot. By changing the bias, and therefore loading resistance, a very constant, variable attenuation is produced over the waveguide band.

TL;DR: In this article, coplanar waveguide (CPW) lines formed by ink-jet printed conductors on flexible Kapton substrates at frequencies up to 60 GHz were analyzed and shown to have losses of approximately 1.5 dB/mm but that this relatively high loss is predominantly due to the loss tangent of the substrates and not the lower conductivity of the silver inks used in this implementation.
Abstract: © 2014 IEEE.This paper characterizes coplanar waveguide (CPW) lines formed by ink-jet printed conductors on flexible Kapton substrates at frequencies up to 60 GHz. It is shown that the lines have losses of approximately 1.5 dB/mm but that this relatively high loss is predominantly due to the loss tangent of the substrates and not the lower conductivity of the silver inks used in this implementation. On an Alumina sample the loss is shown to be 0.8 dB/mm for the same ink-jet printed lines. CST simulation has been used to verify the calculated results.

TL;DR: In this paper, an integrated antenna-battery was designed in order to function at 2.45GHz, with short range Bluetooth applications considered, and the model was derived from a previous study in which an integrated system was first explored.
Abstract: An integrated antenna-battery was designed in order to function at 2.45GHz, with short range Bluetooth applications considered. The model was derived from a previous study in which an integrated system was first explored. The tan δ was investigated for the substrate and this new structure was found to give favourable gains and efficiencies compared to the previous study. Experimental parameters were also applied to the model in the presence of a dielectric material. These experimental parameters gave improved results over the initial assumptions.

TL;DR: In this article, a broadband planar microwave transition is presented for use in the Ku Band, where the electric field is rotated from vertical orientation at the microstrip input port to horizontal on the top dielectric surface at the output port.
Abstract: A novel broadband planar microwave transition is presented for use in the Ku Band. The transition is from a microstrip transmission line to a rotated half-mode substrate integrated waveguide, using a high dielectric constant PTFE laminate. A key feature of the transition is that the electric field is rotated from vertical orientation at the microstrip input port to horizontal on the top dielectric surface at the output port.
