An active membrane phased array radar

We have developed the first membrane-based active phased array in L-band (1.26GHz). The array uses membrane-compatible transmit/receive (T/R) modules (membrane T/R) for each antenna element. We use phase shifters within each T/R module for electronic beam steering. We discuss the T/R module design and integration with the membrane. We also present transmit and receive beam-steering results for the array.
