Researchers from Southeast University have developed a compact, dual-band, dual-polarized phased array for B5G/6G millimeter-wave communication. The array integrates four independent beamforming ...

To put it simply, a phased array antenna is a device that improves communication efficiency by arranging many small antenna elements on a flat surface and controlling them as a single antenna, such as ...

At nearly 2,400 square feet, BlueBird 6 is over three times the size and 10x the capacity of AST SpaceMobile’s six satellites currently in orbit. The satellite is designed to enable peak data rates of ...

Abstract: In this paper, a low-cost K-band phased array antenna is designed for LEO satellite communication. The design reduces the number of T/R components by allowing multiple elements to share a ...

Abstract: Calibration is crucial for ensuring the performance of phased array since amplitude-phase imbalance between elements results in significant performance degradation. While amplitude-only ...
