Our phased-array developments are initially aimed at the forthcoming SpaceX (and others) LEO satellite constellations.
These phased arrays achieve unusually high transmit efficiency, around 40%, and a superior noise figure of ~1dB on receive. Their light weight and low power consumption make them ideal for mobile applications (e.g. cars, trucks, buses, boats) and their conformability suits them to planes and drones. The technology is inherently scalable from Ku-band right up to sub-THz. The potential also exists to operate these antennas in dual-polarised mode. Future developments anticipate enabling the adjustment of polarisation on a per-element basis.
Their high immunity to lasers and EMP, as well as their conformability, make them ideal too for military and covert applications.
The following description gives array diameters for zenith gains at 31dB and 34dB.
A scanning sector of +/-50deg is taken as a target for development, which is consistent with the SpaceX registration paperwork.
Our phased array solution for gateway earth stations (user terminal) are for prospective LEO constellations. These antennas are capable of generating high-gain steered beams to communicate with satellites within the constellations from a single gateway site in Ka-band and V-band.
