This paper discusses a highly directive Substrate Integrated Waveguide (SIW) based Vivaldi antenna in D-band, integrated in a glass interposer. Proposed antenna has a wide bandwidth covering almost the entire D-band from 110 - 163 GHz, with a peak gain of 9.02 dB at 137.2 GHz. Beyond 100 GHz, the dimensions of the SIW in glass are small and thus are convenient to feed antennas for smart devices. The antipodal corrugations present on the arms of the Vivaldi antenna improve the characteristics of the proposed antenna. The SIWs are built on a 2-metal layer stack-up with a $100 mu m$ glass core (EN-A1) from AGC inc. with $15 mu m$ of ABF GL-102 laminated on either side of the glass substrate.

A polarization-maintaining fiber was developed for communication applications within multi-channel and polarization-division multiplexing modalities. The fiber was designed for signal transmission at 128 GHz carrier frequency. It was 3D printed using a 35° inclined nozzle that enables length-unlimited fabrication of terahertz fibers featuring complex transverse geometries. More importantly, a significant reduction (~25%-40%) in fiber transmission loss was achieved after annealing the fabricated fiber at a temperature close to its melting point, resulting in the reduced fiber losses (by power) approaching ~5-10 dB and ~7-11 dB over 110–150 GHz for the two orthogonally polarized modes. The communication demonstrates show that the signal transmission with bit error rates of ~10-11-10-5 was supported at 128 GHz over 1–6 Gbps by the two orthogonal modes of the annealed fiber. The experimental characterization demonstrated the promising prospect of such a novel technique for the fabrication of advanced THz fibers for fiber-assisted communication applications.

A wide-band, passive, and compact RC PPF quadrature network has been implemented in 22nm CMOS FDSOI technology for mm-wave phase shifters of 5G phased arrays or quadrature LO generation and image rejection in mm-wave heterodyne receivers. This paper presents the design procedure and the analysis of the proposed structure that uses a completely passive gain boast approach to enhance the insertion loss while maintaining the good features of the conventional RC PPF quadrature networks. The quadrature network shows measured quadrature phase error of < 2.5± at 24–40 GHz, the amplitude mismatch of < 0.2 dB at 24–40 GHz and the mean gain is $boldsymbol{-1}sim$ -4 dB at 30–40 GHz. The proposed quadrature network does not consume any DC power, and the chip area is $boldsymbol{330} mu mathbf{m} times boldsymbol{240} mumathbf{m}$.

This paper presents a novel frequency modulated continuous wave (FMCW) radar response simulation method with a focus on human gesture detection. Through use of 3D motion captured by an infrared (IR) camera system and data processing, a realistic and computationally efficient simulation is produced. The gestures considered are a hand raise (up-down), right-left arm sweep, and push forward. The high efficiency in simulation is due to a simplified yet effective approach to radar cross section (RCS) calculation and radar-detected signal integration. This allows for the simulation to run smoothly while still resulting in realistic approximations of both range profile and doppler response of gestures. The simulated results are validated with experimental results detected by an Infineon 60-GHz radar.

Dynamic filters are filters that can be tuned in real time, faster than the symbol rate of a signal with time constants longer than the symbol periods. Utilizing the time-varying transmission lines, which offer a low noise, broadband, and non-reciprocal behavior, dynamic filters can be constructed and employed in the rejection of self-interference in the front ends of full-duplex communications systems. Such systems pave the way for the possibility of higher-isolation and robustness compared to other prototypical forms of isolation.

The paper presents a low-profile wideband dual-polarized for Antenna-in-Package (AiP) system. The antenna consists of a middle patch surrounded by artificial magnetic conductor (AMC) structure. Compared to the conventional patch antenna, the operating frequency bandwidth is increased from 6% to 20.7%. The antenna has a maximum gain of 7.8 dBi with excellent gain flatness over the operating frequency range. The overall size is about $0.56 lambda_{0} times 0.56lambda_{0}times 0.077lambda_{0}$. Meanwhile, the $2times 2$ antenna array has also been discussed.

Carrying out a systematic wave propagation simulation based on the backscattering behavior of traffic objects leads to more realistic simulation results. High-resolution RCS measurements in the radial and angular domain can be used for preparing the backscattering model of the traffic objects. For this purpose, the measurement setup is explained for collecting a high number of scattering points of complex traffic objects. Subsequently, the collected scattering points are processed to introduce significant scattering centers according to their RCS patterns. Those virtual scattering centers can be employed as the simplified radar model of traffic participants in the simulation tools to speed up simulations and improve their accuracy. This paper presents the systematic wave propagation simulation steps based on the simplified radar model from the high-resolution RCS measurements.

This paper presents the implementation of a chip-embedded glass interposer targeting 5G applications. Two approaches for low-loss interconnect design on the interposer are demonstrated for the first time on 5G bands by modeling, fabrication, and measurements. Enabled by the interconnects, the fabricated chip-embedded interposer performs low loss and wideband matching over 40 GHz. The excellent performance proves the chip-embedded glass interposer a promising package solution for 5G front-end modules.

A compact nonlinear circuit model is developed for frequency-selective limiters (FSLs) based on thin film magnetic materials. The model contains three-port spin units that represent the dynamic spin precession behaviors. They are combined with transmission line lumped element model to form a complete circuit for FSLs. The field nonuniformity is addressed by splitting the original transmission line inductance. The circuit model is implemented in Advanced Design System (ADS) and is capable of predicting the insertion loss and power threshold of a CPW-FSL.
