We present a new design of a 60 GHz mesh networks based on IEEE 802.11ad. By using an edge/vertex-coloring algorithm to carefully allocate the channels in the mesh network, the co-channel interference of the mesh network, particularly intra-node interference, can be significantly reduced. In our prototype, we found that with 90° angle separation, there is negligible intra-node interference and rate loss. Furthermore, our indoor demonstrations with multi-hop transmissions showed that end-to-end throughput as high as 1.7 Gbps can be achieved.

An analytical approach introduced in 1960 by Russian scientist Tereshin [1]–[2], for decoupling two antennas using an impedance surface is presented. An impedance surface expression is practically realized using corrugations of varied depth onto a cylindrical RF repeater platform and fabricated using 3D-printing. The coupling is measured and obtained results show that the impedance structure decreases the coupling by 11 dB over a wide range in KiKa-band.

In this paper, we propose to employ the Markov jump linear system to model the characteristics of millimeter wave (mmWave) signals, such as signal strength and angle-of-arrival (AoA), for mobile users. We integrate the spatial correlation between line-of-sight (LoS) and none-line-of-sight (NLoS) beams to the stochastic framework for better modeling mmWave. To handle the channel dynamics in mmWave communications, we derive a Markov gain-state channel model based on channel measurements in an indoor environment from our field measurement. The proposed stochastic model is used to estimate the transition probability of each channel. Then it is integrated into the Markov jump linear system framework to construct the linear estimator for channel variables, such as AoA and channel gain. The simulation result demonstrates the outperformance of the proposed framework against the previous Kalman-filtering-based tracking algorithm.

This work presents a modular wideband transmitter channelizer for high data rate communication applications, manufactured in a 130 nm SiGe:C BiCMOS technology with fT / fmax= 300/500 GHz. Three independent I/Q baseband signals are upconverted to different intermediate frequencies and then bonded in current domain. A local oscillator leakage cancellation functionality is implemented on chip within the input stage to enhance the dynamic range. Single ended inputs were utilized in order to reduce the pin count, for a more practical realization and higher potential toward future system scaling. The transmitter channelizer achieves an output 3-dB bandwidth of 15 GHz. LO rejection of 74 dBc at the center frequency was measured after calibration. It dissipates 355 m Wand occupies 1.5 mm2. With these specifications the presented circuitry suits well as a practical solution for wideband channelization for high data rate transmission scenario's, such as THz and sub-THz communications applications, with a potential scaling-up to higher number of channels.

We describe a set of compact millimeter-wave frequency converters for wideband digital signals. Frequency upconverters and downconverters have been developed for frequencies from WR-28 (26–40 GHz) to WR-2.2 (325–500 GHz). Bandpass filters with passband return loss> 20dB and stopband rejection> 50dB within 1 GHz from band edges were developed for use with these upconverters. Preliminary WR-12 link tests are shown.

In this paper, a novel millimetre wave (mm-Wave) flat lens antenna system and its feed network co-designed on a mainstream print circuit board (PCB) technology is presented. It is capable of achieve 3600 coverage scan in Azimuth plane with> 14 dBi measured peak gain and the measured return loss is < 10 dB. Steering in the Elevation plane is designed to be 150upwards; this is controlled by the metal flanges opening angles as they are soldered on both side of the lens. This lens antenna system can be a great candidate for 5G access point operates at mm-Wave. The same technique could be also applied in smaller devices such as cellular phone or tablets.

A planar dually-polarized six-port junction is presented for polarimetry remote sensing. The novelty of the proposed polarization-inclusive remote sensing concept lies in the way the orthogonal polarizations are measured and compared to the reference signal. The core of the proposed system is the dually-polarized individual components such as the dually polarized waveguides, hybrid couplers and phase shifters. The signal flow in the proposed system is explained in details. An example for the analytical procedure to design millimeter wave dually-polarized phase shifter is explained in details.

Measurements of radio-frequency (RF) electric fields in the MHz-to sub-THz range using EIT spectroscopy of Rydberg states in atomic vapors have garnered significant interest in recent years. Here we describe recent work extending the approach to measurements of coherent high-intensity RF electric fields above 1 kV/m and continuous-frequency RF measurement capability. The spectra are modeled using a non-perturbative Floquet model that accounts for higher-order interactions and state mixing. The spectroscopic data also reveal nonlinear amplifier behavior and noise.

An important unmanned aircraft system (UAS) application area is in rescue functions in remote areas, where ground station control may not be applicable. In such settings, an air-satellite (AS) communication link may be required. For transmissions in the millimeter wave (mmWave) frequency bands, rain attenuation can be a dominant fading component in the AS link, especially in so-called “worst month” conditions. Several models have been established by the International Telecommunications Union (ITV) to quantify rain attenuation. However, since the models are for global use, results are not always sufficiently accurate in local areas. Hence the use of local precipitation data can improve rain attenuation estimation accuracy. In this paper, we investigate attenuations in the AS channel in two frequency bands (30 and 45 GHz) for Columbia, SC. We use local rain gauge data from the National Oceanic and Atmospheric Administration (NOAA), along with the regional ITV data, as inputs to the ITV tropospheric time series attenuation model. Statistical results for attenuation distributions and time series are analyzed for the worst month. We show that use of local measured rain gauge data can yield rain fades significantly larger than those predicted by the regional ITV data-on the order of 20 dB larger, for probabilities (~ fractions of time) ranging from 0.001 to 0.04.

A suit of enabling passive components covering entire V-and W-bands, i.e. 45–110 GHz, is built for the support of future RF repeater research and development efforts. Concerns such as loss, power handling, dispersion, and singlemode bandwidth are considered to design a custom double-ridge waveguide and components including antennas, bends, twists, dividers, hybrids, couplers, filters, and decoupling surfaces, just to name a few. Results show that the developed technology can pave the way for efficient, low-cost integrated wideband or multiband millimeter wave systems.
