Abstract :
This paper presents a new architecture for low-cost mobile terminal antennas suitable for linear-polarized satellite communications systems. It is based on a sparse phased array that uses 1-bit phase controls. In this way it is possible to reduce the array cost by employing simpler and fewer controls. Measurements of a prototype demonstrate the feasibility of the approach.
