The paper considers micromachined dielectric and metallic waveguides for THz applications. Analytical analysis and simulation of losses for ideal structures are provided. Effect of fabrication nonidealities, such as surface roughness is also considered. In dielectric waveguide, the dielectric losses are the main loss mechanism, and Silicon tan8 is low above 1 THz, but increases rapidly at lower frequencies. The loss in metallic waveguides increases with increasing frequency. For ideal structures, the Silicon dielectric slot waveguide shows lower loss over 1.2 THz than the metallic waveguide. The effect of rough metal surface in the metallic waveguide increases the loss, making the dielectric waveguide interesting at even lower frequencies.

A 64-element planar phased array is presented, operating between 27.5 and 30 Gigahertz (GHz). The array architecture is based on a quad core beamforming Radio Frequency Integrated Circuit (RFIC) and has a measured Effective Isotropic Radiated Power (EIRP) of 50 dBm. The phased array is packaged with an embedded controller and thermal management features that allow the array to rapidly prototype operational 5G scenarios. Power consumption for the array is 18 Watts (W) in transmit mode, including control and power regulation overhead. Error vector magnitude measured to be better than −40 decibels (dB) with a 256-quadrature amplitude modulation (QAM) signal. This 64-element phased array provides a foundation for prototyping next-generation 5G millimeter wave systems in real environments.

The possibilities of hardware miniaturization and bandwidth enhancement at millimeter-wave frequencies are regarded with great interest, specially for the incoming 5G communication environment. However, conventional manufacturing techniques struggle to provide the accuracy and tolerances required in radiofrequency devices at this frequency. In this work, a W-band circularly polarized 16×16 antenna array with a corporate waveguide feeding network is presented. Diffusion bonding manufacturing technique has enabled a working prototype with satisfactory experimental results, namely a 5.6 % effective bandwidth at 90 GHz with efficiency over 50 % and axial ratio under 3 dB.

In millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) systems, hybrid beamforming structure can be used to improve spectral efficiency by utilizing less radio-frequency (RF) chains. In this paper, we consider the downlink communication of a mmWave massive MIMO system and propose a novel hybrid beamforming algorithm based on extended block diagonalization (BD) and equal gain transmission (EGT) method with near optimal performance and low complexity. At the RF analog domain, we harvest the large array gain by using the EGT method and discrete Fourier transform (DFT) matrix. At the baseband digital domain, the extended BD algorithm is performed. The extended BD algorithm considers both the interference null space as well as the characteristic of the user's signal space while the traditional BD algorithm only considers the interference null space. Then we also analyze the performance of the proposed algorithm in different channel models. According to the simulation results, we find that the proposed algorithm performs well both in sparse channels and Rayleigh channels. To the best of author's knowledge, the performance of the proposed algorithm is better than other low complexity hybrid beamforming algorithms.

A three antenna extrapolation facility was recently built in National Institute of Metrology (NIM), China. It extend the antenna measurement frequency up to 110GHz, and the gain uncertainty lower than 0.1dB can be achieved. Based on the extrapolation range facility, a Spherical Near Field (SNF) scan up to 110GHz is developed. Accurate millimeter-wave antenna gain measurements using the three-antenna extrapolation technique and reference antenna method with port corrections are presented, respectively. The patterns obtained from SNF scan are also given. It is verified that NIM could provide highly accurate millimeter-wave antenna measurements facing industrial requirements.

Active antennas enable novel spatial techniques and beam-forming technology crucial to overcoming millimeter wave propagation challenges for fifth generation (5G) communication systems. At millimeter wave frequencies, a large effective aperture can be accommodated in a physically small area to overcome the high channel loss in these spectrum bands. The ability to dynamically steer and shape active antenna beam(s) to track users., overcome changing channel conditions, and focus the radiated energy into the desired direction provides additional degrees of flexibility and enables better performance for 5G radio system designs. To provide an over-the-air interface for previous generations of radio access networks, traditional architectures have relied upon separate, passive antennas connected by radio frequency cables to active radio transceivers. Active antenna systems, also known as phased array antenna systems, are an advancement from these previous radio access architectures. To implement an active antenna, a array of active radiating elements is utilized to combine passive antenna functions with active amplification and signal conditioning capabilities. Active antennas are an enabling technology for millimeter wave 5G communication systems that create a fundamental architecture shift requiring new Figures of Merit (FoMs). The 5G active antenna FoMs defined in this paper provide methods for antenna performance comparisons and wireless system evaluation.

In this paper, we propose a direct digital RF transmitter using a I-bit band-pass delta-sigma modulator for micro-wave/millimeter-wave applications. This transmitter directly generates a RF signal from the lower rate 1-bit stream by utilizing it's higher order Nyquist zone. We made signal power and SNR comparisons between three types of 1-blt DAC signals; non-return-to-zero (NRZ), 50% duty return-to-zero (RZ) and Manchester coding. By using 1Vp-p / 8 Gbps DAC output, Manchester coding shows the highest output signal power of −20.3 dBm and SNR of more than 40 dB in the 7th Nyquist zone (around 26 GHz). Based on this study, we have tried to adopt this technique to generate a 26 GHz-band 5 Mbps QPSK modulated signal and have confirmed that an EVM of 2.4% can be obtained in the 7th Nyquist zone.

In this paper, we analyze the effects of the positions of a millimeter-wave (mmWave) antenna on a vehicle for typical vehicle-to-vehicle (V2V) scenarios. Propagation does neither effectively penetrate nor diffract around vehicles as the wavelength becomes shorter, the positions of an antenna on a vehicle is a crucial question. Path loss measurement was performed at 28 GHz in an open space to minimize the effect of the surrounding objects. Based on the measurement, we investigated path loss characteristics for various transmitter and receiver positions.

Taming the Terahertz waves (100 GHz-10 THz) is considered the next frontier in wireless communications. While components for the ultra-high bandwidth Terahertz wireless communications were in rapid development over the past several years, however, their commercial availability is still lacking. Nevertheless, as we demonstrate in this work, due to recent advances in the microwave and infrared photonics hardware, it is now possible to assemble high performance hybrid THz communication systems for real-life applications. We present design and performance evaluation of the photonics-based Terahertz wireless communication system for the transmission of uncompressed 4K video feed that is built using all commercially available system components. The Terahertz carrier frequency is fixed at 138 GHz and the system is characterized by measuring the bit error rate for the pseudo random bit sequences at 5.5 Gbps. By optimizing the link geometry and decision parameters, an error-free (BER<10−10) transmission at a link distance of 1m is achieved. Finally, we detail integration of a professional 4K camera into the THz communication link and demonstrate live streaming of the uncompressed HD and 4K video followed by analysis of the link quality.
