This paper presents a recent investigation of dual-mode microstrip filter with non-resonating nodes and nonuniform Q lossy technique. By utilizing the dual-path and dual-mode property of dual-mode open-loop resonator, non-uniform Q distribution is deployed for passband flatness improvement. As there is no coupling between even-mode and odd-mode, the odd-mode Q-factor can be properly reduced by loading resistors over the symmetric plane of each resonators. The coupling matrix analysis are described. Design of this type of 4-pole dual-mode bandpass filter is demonstrated experimentally.

This paper demonstrates how engineered electromagnetic surfaces can be designed and deployed in an urban corridor to enable non-line-of-sight (NLOS) millimetre-wave communications between connected vehicles to support massive automotive sensing. Ray-tracing is used to show the potential improvement in NLOS coverage at 28 GHz, enabling vehicle-to-vehicle high-data-rate transfer of sensor data.

Thick-film barium-strontium-titanate varactors package-integrated with GaN HEMTs are high-efficiency and robust tunable devices that enable frequency agility and efficiency optimization. The tunable transistors presented here achieve 44.4 dBm output power, a peak PAE of 77% and a PAE configurability of 5.6 percentage points. Tunability in saturation remains almost constant for temperature and frequency sweeps from 20 to 80°C and 1.5 to 2.45 GHz, respectively. LTE and WCDMA measurements of the modules used in a power amplifier show good linearity results with −45 dBc ACLR for signals with a high peak-to-average power ratio of 9 dB, no degradation due to the varactors is observed.

A multistatic dual frequency radar operating at 91.5 GHz and 150.3 GHz is designed and utilized to measure particle dimensions in a multidisperse particle stream. From the physical relations a size measurement routine is derived. In a numerical study we then investigate how a multistatic antenna configuration can improve the state-of-the-art method which usually is performed with a monostatic radar. Based on the simulation results, we present the layout of the radar sensor and experimental setup. Finally, measurement results are provided and discussed.

This paper reports on a design methodology and measurement results of a fully integrated low noise amplifier (LNA) on a thinned substrate for Internet of Things (IoT) applications. Several key RF performance parameters of the LNA with different substrate thickness are evaluated through full-wave electromagnetic (EM) simulations. The proposed LNA operating at 5.5 GHz is fabricated in a cost-effective 0.25 μm SiGe BiCMOS technology (IHP process SGB25V; ft = 75 GHz). The Si chip is thinned to ~38 μm in order to be embedded seamlessly into a flexible foil system. The small-signal gain of the LNA, measured on the chuck is 14.32 dB before thinning. The measured center frequency on the thin silicon (thickness of 38 μm) is shifted about 700 MHz towards higher frequencies compared to the thick silicon due to the image mirror currents within the conducting material at the backside of the chip. The measured noise figure (NF) with the thick and thin substrate on the conducting material is around 3.36 dB at 5.5 GHz and 3.74 dB at 6.3 GHz, respectively.

A variable gain low noise amplifier (VGLNA) for millimeter-wave (MMW) wireless communication is proposed in this paper. This VGLNA is implemented using 90-nm CMOS process. It shows small signal gain greater than 20.9 dB from 68.9 to 87.6 GHz with 2.5-dB variation and a dc consumption 56 mW. The gain control range is 2.3 to 21.1 dB at center frequency. The measured minimum noise figure (NF) is 5.3 dB at 80 GHz. This work shows the best noise performance of LNAs in 90-nm CMOS at similar frequencies and comparable figure of merit to those MMW LNAs in better IC process.

Losses in the phase shifters of phased arrays are one of the main limitations of these reconfigurable antennas. This contribution presents the design and measured results of variable phase shifters on triplicate suspended transmission lines in the microwave X-band for variable pointing radar applications. The antenna assembly remains passive and with a very low level of losses in the power distribution network and the phase shifters. PIN or varactor diodes are used to control the load on the transmission line. Each of these components has advantages and disadvantages that are discussed are presented in the communication.

This paper presents the instrumentation and use of a novel electroporation generator, configured of MOSFETs in a push-pull configuration, with an artificial $50 Omega$ buffer for possible real-time neutralization of cancer stem cells. The results from an initial bench study investigates the development of an electroporation generator capable of delivering non-thermal treatment with an original cuvette housing unit and its effects on isolated cancer stem cell. Initial permeabilization investigation of cancer stem cells were conducted, indicating that the developed protocols and devices have a strong potential future use in achieving electro-manipulation of cancer stem cells.

A dual-band bandpass filter consisting of multiconductor transmission lines (MTL) and shunt stubs has been designed. The used topology, based on the interconnection of two identical MTL and a shunt open stub, has a frequency response that can be modelled by using the generalized Chebyshev functions. A prototype of a 4 fingers-MTL is manufactured and measured and a good agreement between analytical and measured results is obtained. Furthermore, it is easy to get a design criterion that enables getting good responses varying just a few parameters.

This paper describes the feasibility study of a Ka-band transceiver designed for small satellite and CubeSat operations. The transponder ensures up to 100 Mbits−1 of data rate with a target power consumption of 20W and an overall volume of 1.5U, not including the antenna. To reduce the costs, commercial off-the-shelf electronic components are used whenever possible. Exploiting a data communication interface like the one proposed, the small satellites market could be opened to new applications such as remote sensing, Earth observation and commercial telecommunications.
