Small-scale prototype of a Ku-band phased array for mobile satellite communications

This paper describes a demonstrator with a small size, incorporating the concepts developed in the ESA-funded project NATALIA. This demonstrator is a smaller version (16 patches) of the final prototype (156 patches). The small prototype is described in detail and measurement results of the farfield, nearfields, power consumption and thermal behaviour are presented. It is shown that the performance is according to expectation and that the design is very robust. The outcome of all experiments verifies the NATALIA concepts.
