Ka-band 27.5-30GHz 256 Elements Phased Array Antenna Tx Subarray

This field‑validated Ka‑band 256‑element 2D expandable phased array antenna is purpose‑built for high‑grade RF communications, optimized for satellite communication systems. It adopts dedicated transmit and receive subarrays: the transmit subarray covers 27.5–30 GHz, while the receive subarray operates within 17.5–21.2 GHz, and both support ±60° two‑dimensional beam scanning. It offers switchable circular and linear full polarization together with independent beam control. Both subarrays support unlimited 2D expansion and flexible splicing to build large‑scale arrays, satisfying variable project scale demands.

On key RF metrics, the transmit subarray achieves boresight EIRP ≥67 dBm, and the receive subarray provides boresight G/T ≥3.11 dB/K. Scanning loss and axial ratio remain well controlled at low levels across off‑axis steering angles, delivering superior overall RF performance. The transmit subarray runs on 12V DC with power consumption ≤130W and footprint 73.6×73.6×30mm. The receive subarray uses 28V DC, consumes ≤34W, and measures 118.4×118.4×20mm.

Both subarrays maintain stable performance from ‑40 ℃ to +70 ℃ for operation and storage. Boasting excellent environmental resilience, this phased array is well suited for rugged outdoor and industrial deployment environments.
