“…3b, and it consists of the phase center (PC) of the excited element from where the radiation spreads spherically outward. The PC of the element along the x-axis is found from HFSS [40] by minimizing the phase difference (ideally zero) of the far-field vertical component E θ within the 3-dB beamwidth angular range (i.e., −40 • ≤ φ ≤ 40 • ) in the horizontal plane [50]. The measured G 0 , calculated from (3) using measured LoS S-parameters, is shown in Fig.…”

Traditional wired interconnects in multicore multichip (MCMC) systems can be replaced with chip-integrated switched beam antenna arrays to provide reconfigurable chip-to-chip communications. By simply switching the directive beams of the arrays, the chips can be made to dynamically communicate with their surrounding neighbors. Radiation from the arrays in the unintended direction, however, causes interference when multiple pairs of chips are simultaneously communicating. In this paper, the noise and interference limitations of such concurrent chip-to-chip communication systems are analyzed at 60 GHz for the channels defined in the IEEE 802.11ay standard. Each array consists of eight substrate integrated waveguide (SIW) horn elements printed on a thin dielectric substrate. The elements can be individually excited to produce eight directive endfire beams, providing full 360 • coverage, in the horizontal plane. The substrate acts as a hybrid space-surface wave interconnect (HSSW-I) that allows near-field, space and surface wave coupling to occur between the arrays, and thus, increases interchip transmission. The antenna and link parameters that dictate the signal-to-noise-plus-interference ratio (SNIR) of such systems are established by considering all the major components. The maximum achievable data rates are then determined based on the SNIR, calculated from the measured and simulated transmission coefficients between the arrays.INDEX TERMS 60 GHz, chip-to-chip antenna, hybrid space-surface wave interconnect (HSSW-I), interference, link budget, multicore multichip (MCMC), noise, reconfigurable, substrate integrated waveguide (SIW), switched beam.

“…The beamforming antennas help to improve the coverage, SNR, and effective beam steering [ 80 ]. We broadly categorize the 60 GHz smart beamforming antennas into three types: printed circuit board (PCB)-based antennas [ 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 ], on-chip antennas [ 59 , 98 , 99 , 100 , 101 , 102 , 103 ], and low temperature co-fired ceramic (LTCC)-based antennas [ 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 , 114 , 115 ]. We discuss these antennas here in detail.…”

Industry 4.0 is a new paradigm of digitalization and automation that demands high data rates and real-time ultra-reliable agile communication. Industrial communication at sub-6 GHz industrial, scientific, and medical (ISM) bands has some serious impediments, such as interference, spectral congestion, and limited bandwidth. These limitations hinder the high throughput and reliability requirements of modern industrial applications and mission-critical scenarios. In this paper, we critically assess the potential of the 60 GHz millimeter-wave (mmWave) ISM band as an enabler for ultra-reliable low-latency communication (URLLC) in smart manufacturing, smart factories, and mission-critical operations in Industry 4.0 and beyond. A holistic overview of 60 GHz wireless standards and key performance indicators are discussed. Then the review of 60 GHz smart antenna systems facilitating agile communication for Industry 4.0 and beyond is presented. We envisage that the use of 60 GHz communication and smart antenna systems are crucial for modern industrial communication so that URLLC in Industry 4.0 and beyond could soar to its full potential.

This paper proposed to use surface wave fluid antennas to realize beam-steering functionality and spatial diversity. By utilizing the advantage of the non-radiating feature of surface wave propagation, in contrast to the conventional multiple RF input ports approach reported, the proposed design only required one RF input to achieve the spatial diversity. The proposed surface wave fluid antenna is designed to work in the millimeter-wave frequency band from 20 to 26.5 GHz. The preliminary results show that the radiation direction of the antenna can be controlled by changing the position of the fluid metal radiator.
