“…2) TERRESTRIAL/ARIAL COMMUNICATION FROM K-TO Q-BAND Depending on the specific application, terrestrial 5G base stations and user terminals typically have different requirements (see Section I). While electronically steerable antennas for 5G single-/dual-beam user terminals often rely on analog beamforming [7], [66], [68], [113], [228], [229], [230], [231], base station antennas are making use of massive MIMO through hybrid [58], [232] or digital beamforming schemes [54], [233], [234].

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.

Purpose RF transceiver module is considered a vital part of any wireless communication system. This module consists of two important parts the RF transceiver and analog-to-digital converter (ADC). Usually, both these parts – RF transceiver and ADC – are used to enhance the perspective of size and power. The data processing in 4G communication makes hurdles and need research attention to make it faster and smaller in size. Accuracy and fast processing are the critical challenges in the modern communication system. Design/methodology/approach After theoretical and practical investigations, this research work proposes key new techniques for the RF transceiver module. These techniques will make RF transceiver small, power-efficient and on the other hand, make dual SAR-ADC more effective as well. The proposed design has no intermediate frequency where the RF transceiver is reduced its major blocks from five to four, which includes crystal oscillator, phase lock loop, power amplifier and low noise amplifier. Moreover, the shared circuitry is introduced in the architecture of the SAR-ADC for the production of dual outputs, specifically in bootstrapped switch and comparator. Findings The miniaturized RF transceiver and SAR-ADC are well tested separately before the plantation on the printed circuit board (PCB). The operating voltage and frequency of the RF transceiver module are 1.2 V and 5.8 GHz, where the sampling rate, bandwidth and output power are 25 MHz, 200 MHz and 5 dBm, respectively. The core area of the PCB is 58.13 mm2. The bandwidth efficiency is 93% using surface acoustic wave less transmitter. The circuit is based on the library of 90 nm CMOS technology. Originality/value The entire circuit is highly synchronized with the input and reference clocks to avoid self-interference.

In this article, a digital phase-modulation (PM) phase-shifting (PS) phased-array transmitter is proposed. Both PM and PS are implemented in a PS modulator. Meanwhile, a self-calibration loop is introduced in the PS modulator for improved phase linearity and minimized phase error. The phase control voltages for the PS modulator are generated from the self-calibration loop based on the output signals and reference signals. To reduce the calibration time, a capacitor-array-based state store memory is introduced in the self-calibration loop. Efficiency at 2.5-/6-/12-dB power back-off (PBO) is enhanced by class-G Doherty switched-capacitor power amplifier (SCPA). As a verification of the concept, a 2.1-2.9-GHz four-element phasedarray transmitter is designed and fabricated in a conventional 40-nm CMOS technology. The transmitter features a 10-bit fastlocking phase self-calibration with measured 0.4 • rms phase error and 0.2-dB rms power error. The measured peak saturated output power of each element is 26.95 dBm at 2.4 GHz. Besides, the measured system efficiency at 0-/2.5-/6-/12-dB PBO is 37.25%/34.24%/30.12%/21.23%. For 20-MHz 64-QAM/15-MHz 256-QAM modulation signal, it exhibits EVM of 4.65%/2.84%, average output power of 19.91/16.59 dBm, and average system efficiency of 24.12%/19.21% at 2.4 GHz. By connecting monopole antenna units with a gain of 4.21 dBi, the measured peak effective isotropic radiated power (EIRP) of phased-array transmitter is 42.05 dBm.
