Reconfiguration of parasitically controlled elements in a phased array is used to expand the range of operational functions. Embedded array elements can be frequency tuned, and bandwidth can be improved by using reconfiguration to broaden the bandwidth of the embedded elements. For high gain arrays,...http://www.google.de/patents/US7453413?utm_source=gb-gplus-sharePatent US7453413 - Reconfigurable parasitic control for antenna arrays and subarrays
