The objective is the definition and development of a fully electronic transmit-receive steerable antenna system in Ku-band for aircraft in flight entertainment via satellite. Phase 1 of the project includes several system related subjects such as regulatory aspects, design constraints and trade-off between different architectures as well as a preliminary design for a demonstrator antenna. Phase 2 of the project consist of the design, build and test of the Demonstrator connected array antenna.

With a full electronically steerable antenna, large hemispheric coverage can be obtained without any mechanical moving parts. Transmit and receive frequency bands can be supported in full-duplex, even with independent polarization setting.
The connected array antenna principle has the advantage of having a very wide frequency bandwidth in combination with wide electronic scanning capabilities and high polarization purity.
