Polyomino-Tiled AESA for LEO Satcom on-the-Move Connectivity

The trend towards cost-effective phased arrays (PAs) with simplified architectures is nowadays driven by the development of mobile communication systems and non-terrestrial/satellite networks. This has led to an increased interest towards unconventional PAs characterized, for example, by a modular architecture in which a cluster of antennas is connected to a single transmit and/or receive module in order to reduce the hardware complexity and the costs as compared to fully-populated solutions. In this work, the design of a modular PA architecture with irregular clustering configuration for low Earth orbit (LEO) satcom on-the-move (SOTM) applications is presented.
