This paper presents for the first time the successful fabrication of a bi-material, fully printed W-band quasi-Yagi-Uda antenna using the Aerosol Jet printing (AJP) technology. A 4 mil Liquid Crystal Polymer (LCP) was used as the host substrate, on top of which the ground plane, the dielectric substrate and the metal antenna layer were Aerosol Jet printed. Various sizes of nozzles were used to achieve quality geometry resolution and fast prototyping. Specifically, the ground plane and the metal antenna layer were printed with silver ink using the 150 µm and 100 µm nozzles, respectively. The dielectric substrate however, was deposited using polyimide with the 300 µm nozzle. The S11was measured as −20 dB at the resonance frequency of 92.7 GHz and matches well with the −31.6 dB of simulated S11at 94 GHz. The measured and simulated −10 dB impedance bandwidth were 12.5 GHz and 8.1 GHz, respectively. 7.65 dBi of simulated maximum realized gain and 9 GHz of simulated 3 dB bandwidth were also obtained.

Millimeter-wave sensor network will be conduce to very small and secure wireless tags. Conventional oscillator of millimeter-wave is mainly developed to reduce the phase noise and increase the tuning range and power consumption is larger than 1mW. The ultra-low power consumption oscillator, which has power consumption of less than 1mW, is needed to achieve millimeter-wave sensor network. In this paper, the design methodology is proposed for ultra-low power consumption oscillator. The fabricated IC performs 57.4GHz with 130µW power consumption. The FOM is 10dB higher than those of previously reported.

In this paper, we propose a high-gain series-fed eight-element printed dipole array antenna. Each dipole has the same size, the spacing between each dipole is identical, and the dipoles are connected in a series with a coplanar stripline. Broadband impedance matching is achieved with the balun, which consists of two slot lines of different lengths and widths on one side of the substrate and a tapered microstrip line on the other side of the substrate. The impedance bandwidth of the eight-element printed dipole array antenna is 34.3%, and the gain is 9.2-13.3 dBi. The radiation patterns exhibit endfire characteristics. The overall size of the designed array antenna is $15times0.254 times 47.8mathrm{mm}^{3}(1.4times 0.024times4.5lambda_{0}^{3})$.

A V-band rod antenna with constant gain based on spoof surface plasmon polaritons (SPPs) is proposed in this paper. In this design, a periodic metallic grating operates as a SPP transmission line, which can provide high EM field confinement and achieve a low insertion loss (only 0.079dB/mm at 60GHz). Meanwhile, due to the SPPs unique dispersion characteristic, a broadband rod antenna is designed with high gain. This rod antenna is conveniently fabricated by 3D printing followed by metalization. The simulated results show that the proposed rod antenna can cover V-band from 50 to 75GHz with| S11| < −15dB and achieve a gain of 15.8 dBi with less than 1.2dBi variation. The measured −10dB bandwidth is from 50GHz to 70GHz with 12.87dBi-16.5dBi gain.

Wireless body area network (WBAN) using millimeter wave is expected to reduce inter-Wbaninterference, but it is necessary to consider the connectivity of the millimeter wave intra-Wbancommunication. In this paper, we propose the directional millimeter-wave WBAN in the walking pause considering directional selectivity between intra-Wbancommunication and inter-Wbaninterference. The measurements of on-body propagation loss are shown at 60 GHz comparing with geometrical line-of-sight (LoS) experimentation using a flashlight for directional millimeter-wave WBAN. From the measurements result, there is no severe problem due to the body attenuation of intra-Wbancommunication with the directional antenna for Tx and Rx antennas.

This paper presents the design, fabrication, and performance of a W-band amplitude-only azimuthal direction finding antenna subsystem, designed to cover 75–110 GHz. The design utilizes curved-aperture pyramidal horn antennas to achieve near frequency independent radiation patterns over the band of interest, and 2-element linear arrays to increase receiver detection range. Two arrays are squinted apart by 30° to realize a high slope and near monopulse direction finding function.

A salient feature of millimeter-wave (mmW) wireless systems is their large bandwidths. A direct consequence is that radio frequency (RF) non-idealities, such as phase noise, I-Q imbalance, and non-ideal frequency response of bandpass filters, become more pronounced compared to existing systems operating below 6 GHz. However, investigations of the impact of such nonidealities and techniques for their compensation are limited. In this paper, the problem of I-Q mismatch is investigated, motivated by the authors' recent work on mmW prototype design and development. First, a model for the non-ideal system is developed by modeling the in-phase (I) and quadrature (Q) passband channels separately, rather than the common complex baseband representation. The resulting channel matrix reveals the structure of interference introduced across I-Q channels and frequencies. Second, a new approach is developed for estimating the non-ideal channel using the new model. Third, a linear receiver architecture is developed to compensate for the interference caused by the I-Q mismatch. Finally, the performance of the new proposed system is compared to a baseline conventional system which ignores I-Q mismatch. The results indicate significant loss in performance even for modest values of I -Q mismatch parameters. In particular, the baseline system exhibits a saturation of output signal-to-interference-and-noise ratio (SINR) regardless of the input SNR. The new proposed system does not suffer from such saturation and its SINR can be increased indefinitely by increasing the input SNR. The analytical results are validated with experimental evaluation on a 28 GHz mmW wireless testbed.

Millimeter wave (mmWave) cell sizes are meant to be small, and hence base station heights will often be low. This will increase the probability of a link traversing vegetation. For such cases, it is important to know the range of expected attenuations. In this paper, radio wave attenuation and depolarization effects through several broadleaf evergreen shrubs are reported, based upon measurements at two frequencies, 5 and 31 GHz. From this, we analyze the relationship between this attenuation and the two frequencies, and the shrub density, depth, and measurement geometry. Three different shrub species with different densities and depths, and for different measurement geometries, were employed. Specific attenuations at 31 GHz can exceed 20 dB/m for the densest shrubs. These results will be useful for link budget design, and outdoor and outdoor-indoor models for future mmWave communication.

This paper presents a 24–44 GHz ultra-wideband (UWB) low-noise amplifier (LNA); simultaneously covering all major 5G cellular frequency bands. The LNA has been designed in 45nm CMOS SOI technology, has a maximum gain of 20 dB with more than 65% 3dB bandwidth (24-47.5 GHz), and a noise figure less than 5.5 dB (typical 4.7 dB) in the band. A narrowband 28 GHz LNA is presented for comparison and evaluation of merits of a wideband design.

In this work, we describe the design, development and status of implementation of a Water Vapor Radiometer (WVR) at 183 GHz. The architecture of the instrument is based on a pseudo-correlation radiometer with analog sideband separation and includes 1/f mitigation by phase-switching the local oscillator (LO) signal. The improved sensitivity of the development comes from the use of high performance Monolithic Microwave Integrated Circuits (MMIC) chips instead of the typical Schottky diode mixers at the input. We forecast sensitivity per sub-band of 170 mK, at an output instrument rate of 1 Hz.
