Photonic integration and components development for a K <inf>u</inf>-band phased array antenna system

In this paper the development of a phased array antenna system using a photonic beamformer is reported. The paper emphasizes on the photonic integration between two main components of the beamformer, namely the photonic beamformer chip and the electroabsorption modulator array. System level simulation is used to determine the required performance of each component. The measurements on the component characteristics are presented

Development of the SANDRA antenna for airborne satellite communication

Novel avionics communication systems are required for increasing flight safety and operational integrity, for optimizing economy of operations and for enhancing passenger services. One of the key technologies to be developed is an antenna system that will provide broadband connectivity within aircraft cabins at an affordable price. This paper describes the development of an electronically steered Ku-band phased array antenna with low aerodynamic profile. The antenna front-end consists of at least 1800 antenna elements, of which the beam has to be steered continuously to geostationary satellites. Best performance for the beam steering is expected from a hybrid architecture with small sub-apertures having their local own beamformers (using phase shifters). The beamformer to steer the sub-apertures of the entire antenna uses True Time Delays with an optical ring resonator

Towards a broadband and squint-free ku-band phased array antenna system for airborne satellite communications

In this paper, we describe the design and the development of a Ku-band phased array antenna system for the reception of a digital video broadcasting by satellite (DVB-S)signal. A concept of optical beamforming is implemented to provide a squint-free beam steering over the entire Ku-band (10.7-12.75 GHz) as well as to achieve seamless tunability of the beam pointing direction. The total antenna system is described and the system performance is simulated. Requirements for system components are formulated and the development of these components towards the implementation of the broadband, squint-free phased array antenna system is reported
