Overlapping subarray patch antenna system

摘要

A high altitude communication device is provided using a first array element comprising a plurality of patches and a second array element comprising a plurality of patches. The first array element and the second array element are for receiving communication signals. A patch in the first array element is shared by the second array element. At least one grouping network selects the first array element for a first time interval and selects the second array element for a time interval after the first time interval to convert and form digital combined signals from the communication signals. A method of digitally controlling received signals within a high altitude communication device is also provided.
