Abstract
Methods of operating a transceiver including an antenna having a plurality of antenna feed elements include providing a plurality of gain constraint values associated with respective ones of the plurality of geographic constraint points within a geographic region, selecting initial phase constraint values associated with respective ones of the gain constraint values, generating antenna feed element weights based on the gain constraint values and based on the initial phase constraint values, and determining system response values in response to the antenna feed element weights. Phases of the system response values are compared to the initial phase constraint values, and an antenna beam is formed from the antenna to the geographic region using the antenna feed element weights in response to the comparison of the phases of the system response values to the initial phase constraint values. Related systems and devices are also disclosed.
