Product Detail

This Ka-band receiving phased array antenna integrates advanced active 2D scanning technology, combining antenna radiation and beam steering in a compact design. It supports vertical, horizontal, dual-linear and circular polarization, and uses high-precision beamforming algorithms for adaptive beam control. Operating at 10.7–12.7 GHz with ±60° scanning, it contains 2048 elements and delivers G/T ≥11 dB/K. With power consumption ≤350W and weight ≤12kg, it works reliably from –40°C to +60°C and withstands storage from –55°C to +75°C. The scalable, tileable and low-profile structure makes it ideal for high-demand communication systems.
