Select a Ku-band satellite antenna from the operator’s coverage and access requirements, a site-specific link budget and the minimum service rate required during bad weather. Dish diameter alone cannot guarantee 99.9% availability. At equal frequency and aperture efficiency, increasing diameter from 1.2 m to 1.8 m adds about 3.52 dB of gain; whether that closes

A flat-panel satellite antenna steers its beam across a low-profile aperture. Phased arrays and tunable metasurfaces can both do this electronically, but they use different RF architectures. For LEO service, select the terminal by network compatibility, EIRP and G/T across its scan range, tracking performance, and available electrical power—not by panel thickness alone. Metamaterials and
