About
The LEOLINK64 is an active Ka-band electronically beam-steering phased array antenna developed by Arralis for high-data-rate satellite communications with low Earth orbit (LEO) constellations. The antenna provides TX coverage at 27.5-30 GHz and RX coverage at 17.7-20.2 GHz, with full electronic beam steering across +/-60 degrees in both azimuth and elevation using 64 radiating elements and analog phase shifters with amplitude control.
The flat panel, low-profile geometry is designed for integration onto vehicles, aircraft, UAVs, and maritime platforms requiring SATCOM on the move. Circular polarization (via sequential rotation technique for wide bandwidth) meets ITU regulatory requirements for sidelobe and beamwidth compliance through amplitude tapering. TX EIRP reaches 48 dBi with 22 dB TX gain and 21.9 dB RX gain at boresight, consuming 9.6 W in TX mode and 6.4 W in RX mode.
An optional control board add-on provides additional customization for specific operational requirements. The LEOLINK64 interfaces directly with any SDR or satellite modem and is designed to meet growing demand for flat, electronically steerable antennas serving LEO megaconstellation ground segments, airborne connectivity, and autonomous vehicle satellite links.
