This paper presents reconfigurable antenna arrays based on liquid crystals (LCs) for earth and space applications. Tunable reflect arrays at 35 GHz and tunable phased arrays for Ku- and Ka-bands are discussed in detail in terms of technology, performance, size and cost.
Particular attention is given to LC based cost effective planar phase shifters in order to design multilayer reconfigurable phased array antennas applicable for, i.e., automotive applications.
