“…20a)) for terrestrial communication applications from 23.5-29.5 GHz has been presented in [66] by lowering the radiator's Q-factor through expansion of the unit cell dimensions but in return of a smaller scanning range of 30°and 45°i n the E-and H-plane, respectively. Considerable efforts have also been devoted over almost three decades to cavity-backed patch antennas to alleviate scan blindness effects by means of galvanic isolation [91], [199], [200], [218].

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.
