Phased Array Antenna 17.7-21.2GHz Ka Band 256elements
Product Introduction
This field‑validated Ka-band receiving phased array antenna is purpose‑engineered for high-performance communication systems, integrating advanced active two-dimensional scanning technology. It merges antenna radiation and beam steering functions within a compact low-profile package.
Supporting vertical, horizontal, dual-linear and circular polarization modes, the unit leverages high-precision beamforming algorithms to enable adaptive beam control. Covering 10.7–12.7 GHz with ±60° beam scanning, this 2048-element array achieves G/T ≥11 dB/K.
It consumes ≤350W and weighs ≤12kg, operating stably between –40°C and +60°C, while surviving storage temperatures ranging from –55°C to +75°C. Featuring scalable and tileable mechanical construction, this receive phased array serves as a reliable solution for high-demand communication deployments.
