Fabrication of Fully Inkjet-Printed Vias and SIW Structures on Thick Polymer Substrates

Sangkil Kim

In this paper, a novel fully inkjet-printed via fabrication technology and various inkjet-printed substrate-integrated waveguide (SIW) structures on thick polymer substrates are presented. The electrical properties of polymethyl methacrylate (PMMA) are thoroughly studied up to 8 GHz utilizing the T-resonator method, and inkjet-printable silver nanoparticle ink on PMMA is characterized. A long via fabrication process up to 1 mm utilizing inkjet-printing technology is demonstrated, and its characteristics are presented for the first time. The inkjet-printed vias on 0.8-mm-thick substrate have a resistance of ~0.2. An equivalent circuit model of the inkjet-printed stepped vias is also discussed. An inkjet-printed microstrip-to-SIW interconnect and an SIW cavity resonator utilizing the proposed inkjet-printed via fabrication process are also presented. The design of the components and the fabrication steps are discussed, and the measured performances over the microwave frequency range of the prototypes are presented.

Proximal Radar Sensors for Precision Viticulture

In this paper, we report the accurate estimation of vine grape yield from a 3-D radar imagery technique. Three ground-based frequency-modulated continuous-wave radars operating, respectively, at 24, 77, and 122 GHz are used for the contact-less estimation of grape mass in vineyards. The 3-D radar images are built from the beam scanning of the vine plants and allow estimating the mass of grapes from the computation of appropriate statistical estimators. These estimators are derived from the measured polarization and magnitude of radar echoes. It is shown that the estimation of grape mass from the proposed ground-based radar imagery technique at millimeter-wave frequency range may be accurate within 1%.

Miniaturized Hybrid Ring Coupler Using Electromagnetic Bandgap Loaded Ridge Substrate Integrated Waveguide

A novel compact Ridge Substrate Integrated Waveguide (RSIW)-based hybrid ring coupler is hereby presented. The size miniaturization is accomplished through a twofold approach. First, the RSIW is used to reduce the coupler waveguide transverse dimension. The RSIW of the hybrid ring is then loaded by Electromagnetic Bandgap (EBG) structures, etched in its non-ridged broadwall, exploiting their slow wave effect to reduce the longitudinal dimension. It is demonstrated that the use of EBG-loaded RSIW can lead to a size reduction of more than 48% and 91% with respect to the unloaded RSIW and conventional SIW hybrid ring couplers, respectively.

Electromagnetic Transduction for Wireless Passive Sensors

Wireless sensors market is growing very fast these last years tanks to the availability of cheap, small and efficient micro–sensors, batteries, analog and RF circuits, and to the presence of standardized communication protocols. Even if these active sensors are very attractive for a lot of applications, they suffer from weak energy autonomy and they are not compatible with harsh environment. In order to overcome these problems, we have developed a new kind of wireless sensors using electromagnetic transducers and radar interrogation. These passive sensors (battery–less and without electronic components) have been studied for pressure, temperature, gas and stress applications

Autonomous RFID Sensor Node Using a Single ISM Band for Both Wireless Power Transfer and Data Communication

This paper addresses the implementation of autonomous radiofrequency identification sensor nodes based on wireless power transfer. For size reduction, a switching method is proposed in order to use the same frequency band for both supplying power to the nodes and wirelessly transmitting the nodes’ data. A rectenna harvests the electromagnetic energy delivered by the dedicated radiofrequency source for charging a few-mF supercapacitor. For supercapacitors of 7 mF, it is shown that the proposed autonomous sensor nodes were able to wirelessly communicate with the reader at 868 MHz for 10 min without interruption for a tag-to-reader separation distance of 1 meter. This result was obtained from effective radiated powers of 2 W during the supercapacitor charging and of 100 mW during the wireless data communication.
