“…Aiming to provide higher data rates by pushing spectral efficiency has led to the development of numerous MIMO transceiver chipsets for mm-wave 5G applications up to the E-Band. This includes analog beamformer ICs based on fully connected structures [61], [73], [168], frequency-domain multiplexing [74], and polarization multiplexing [178], to name a few.…”

Satellite, fifth generation (5G), and sixth generation (6G) mobile communication systems operating at micro-and millimeter wave frequencies are an essential pillar in advanced network architectures for high-throughput low latency services. The decisive factors for this current development were the significant technological advances accomplished over the last two decades, which meanwhile enable highly integrated, feature-rich, and cost-effective realizations of complete phased array transceiver topologies. Motivated through the today's trend for heterogeneous constellation types to provide truly global coverage, this contribution reviews the current state-of-the-art of electronically steerable antennas for terrestrial and non-terrestrial communication systems up to 100 GHz. First, the potential benefits and limitations of the most relevant technologies are contrasted and put into context with recent system architectures for adaptive beamforming. Their operating principles along with various experimental implementation and achievements providing advanced capabilities such as multi-band/multi-beam operation, polarization agility, and wideangle scanning are thoroughly presented. Particular emphasis is laid on the review of direct radiating arrays, quasi-optical antenna configurations, and metasurface-based antennas.INDEX TERMS Satellite communications on the move (SOTM), fifth generation (5G), sixth generation (6G), hybrid satellite constellations, aerial networks, electronic steering, phased array, antennas.This article has been accepted for inclusion in a future issue of this journal.

“…The rapid developments of Si-based integrated technologies have enabled versatile electronic devices such as amplifiers, dividers, phase shifters, mixers, and transformers. Based on these fundamental block circuits, more complicated communication systems can be achieved, such as RF front-end, phased array system, and multi-input multi-output (MIMO) transceivers [1][2][3], which are widely used in military and commercial applications. In a highly integrated chip, electrical signals propagate between hundreds and thousands of active and passive devices at very high speeds.…”

This paper presents a base-band differential transmission line for a phased-array receiver in 65 nm CMOS. It mainly consists of two parallel metal lines as signal carriers with surrounding layers to form a close cavity. The 1000-μm long differential transmission line with a line width of 1 μm achieves a transmittance from -2.99 dB to -2.15 dB and a relative phase from -28.54° to 0 over 0-2 GHz. Based on the passive structure, the power consumption is zero, and the core cross-section occupies a compact area of 10 μm *2.11 μm.

“…Phased-array architecture is essential in 5G NR communications to improve signal quality at mmW frequencies. 5G NR phased-array systems with competitive receiver performance have been published with narrowband designs recently [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14]. However, multiple chips are necessary to support the multi-band operation, which increases the system size and complexity.…”

This article introduces a power-efficient 24.25-71-GHz multi-band phased-array receiver supporting all allocated fifth-generation mobile network new radio (5G NR) frequency range 2 (FR2) bands at 24/28/39/47 GHz and the potential 5G NR-U bands in unlicensed 57-71 GHz. A novel harmonic-selection technique is introduced to extend the operating bandwidth with low power consumption. By switching between the fundamental-selected mode, the second-harmonicselected mode, and the third-harmonic-selected mode, only signals in the desired bands can be preserved, while the unselected mixing components are rejected. A dual-mode multi-band lownoise amplifier (LNA) based on a configurable transformer is adopted to realize broadband operation with minimized power consumption and noise figure (NF). The Hartley architecture is employed to further improve the image rejection performance. A hybrid-type polyphase filter (PPF) with a detectorbased high-precision calibration block is utilized in this work to realize the Hartley operation with reduced insertion loss (IL). The proposed phased-array receiver is fabricated in a standard 65-nm bulk CMOS process. With the concerted efforts of all components, the proposed multi-band receiver can support 5G standard-compliant OFDMA-mode modulated signals up to 256QAM with a 400-MHz channel bandwidth from 24 to 71 GHz. Better than 36-dB inter-band blocker rejections can be maintained by this work. With existing of 0-dBc inter-band blockers at worst case frequencies, this receiver
