One Dimensional Phased Array Satellite Antenna
Product Introduction
The One-Dimensional Active Phased Array Satellite Antenna is a high-performance on-board communication device tailored for global in-vehicle and airborne scenarios. Operating in the Ka-band, it supports automatic polarization adjustment and 360° continuous azimuth scanning, with stable communication even at a low elevation angle of 15°. Equipped with one-click auto-satellite acquisition and high-precision tracking (≤0.2°), it meets the needs of long-range communication, dynamic connectivity, and video transmission for military communication vehicles, connected cars, general aviation aircraft, and industrial UAVs. With advanced protocol optimization and fast beam switching, it ensures reliable signal transmission in both stationary and moving states.
-
High beam scanning precision: Phase shifter null compensation technology reduces beam step to <0.2° (from 1.46°), ensuring stable signal and excellent user experience;
-
Low elevation angle performance: Pre-tilted antenna array design supports stable communication at 15° elevation angle, with 3dB less signal loss than conventional phased array antennas;
-
Low-loss RF board: Special microwave plate production process and multi-layer hybrid pressing technology reduce RF line insertion loss by 50% and ensure consistent amplitude and phase;
-
Cost-effective integration: High-density combination of low-cost LNA, PA and multi-channel beam control chips, reducing overall machine cost without compromising performance;
-
Rapid and reliable tracking: One-click auto-satellite acquisition (3min stationary / 5min moving), signal recapture time ≤3s, supporting open-loop + closed-loop hybrid tracking algorithm;
-
Advanced protocol support: Downlink DVB-S2/S2X standard, uplink MF-TDMA mode, with TCP/HTTP acceleration and IP header compression for optimized network performance.
