This paper reports on the design and fabrication of a fully integrated antenna beam steering concept for airborne applications at 17 GHz. The system is based on a single wafer process including a dipole antenna, a balun and a 2-bit distributed MEMS phase shifter (in a 7 x 3 mm high-resistivity-silicon dice). To our knowledge, it is the first time that such integration has been done. First results of individual devices are reported and simulations of the whole concept are originally presented.
