“…2). Depending on where the analog beamformer (ABF) is implemented in the system, a distinction is generally made between radio frequency (RF) [62], [63], [64], [65], [66], local oscillator (LO) [49], [67], [68], intermediate frequency (IF)/baseband (BB) [69], [70], [71], [72], [73], [74] beamforming. Towards increasingly larger phased array systems, the complexity and scalability of the integrated circuits is becoming a major design aspect [44].…”

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.

“…From a pure performance perspective, OTS is a good candidate as a clocking platform for large arrays, for example, as a complement to a local LFTS scheme. 4 While electrical references are utilized in mid-size arrays [48], [49], larger implementations (>40 k elements), for example, [50], may benefit from an optical reference clock. The strongest competitor to OTS in sparse applications is a low-frequency reference that is distributed using RFTS methods.…”

Optical synchronization of large-span arrays offers significant benefits over electrical methods in terms of the weight, cost, power dissipation, and complexity of the clock distribution network. This work presents the analysis and design of the first phased array transmitter synchronized using a fully monolithic CMOS optical receiver. We demonstrate a bulk CMOS, 8-element, 28-GHz phased array building block with an on-chip photodiode (PD) that receives and processes the optical clock and uses an integrated PLL to generate eight independent phase-programmable RF outputs. The system demonstrates beam steering, data transmission, and remote synchronization of array elements at 28 GHz with fiber lengths up to 25 m, in order to show the scaling benefits of our approach. The provision of small footprint and cost-effective CMOS transceivers with integrated optoelectronic receivers enables exciting opportunities for low-cost and ultralight array systems.

We propose here a 4040-element sharedaperture dual-band dual linearly-polarized transmitarray with 1-bit phase resolution and fixed beam at Ka-band. The design is based on a stacked approach where the unit-cell size is compact and is equal to only 0.48×0 and 0.32×0 at 29 GHz and 19 GHz, respectively. The beam-scanning performances of this array are compared to those of an array with the same number of elements and same illumination but comprising unit-cells based on the interleaving approach (lattice size of 0.72×0 and 0.47×0, respectively). The shared-aperture unitcells include four printed U-slotted patch antennas and a connecting metallized via; the desired 180° phase shift is obtained by rotating one of the patches around its corresponding via. Our simulation results demonstrate that the transmitarray based on the stacked approach exhibits excellent beam scanning performance up to ± 70° on the two bands. A prototype pointing at broadside has been optimized and fabricated to validate the numerical simulations.
