17.7-21.2GHz Ka Band 256elements Phased Array Antenna for Beam Control

ZD-PAA-KAR-17/21G

Ka-band receiving phased array antenna integrates advanced active two-dimensional scanning transmission technology, consolidating critical functions such as antenna radiation and beam control into a highly compact architecture. It supports multiple polarization modes including vertical, horizontal, dual-linear, and circular polarization, and employs sophisticated beamforming algorithms for precise and adaptive beam steering. Operating across 10.7–12.7 GHz with a scanning range of ±60°, the antenna comprises 2,048 radiating elements and achieves a G/T of ≥11 dB/K. With power consumption ≤350W and weight ≤12kg, it delivers robust performance under extreme temperatures, operating from –40°C to +60°C and surviving storage conditions from –55°C to +75°C. Its scalable, tileable design enables the formation of larger arrays, while the low-profile, highly integrated form factor ensures suitability for space-constrained and demanding communication platforms.
