ABSTRACT:
A new planar phased array antenna is disclosed having M by N antenna cells with only M+N phase shifters. A grid of M+N feed lines with the M feed lines at a first frequency having a uniquely controllable phase and N feed lines at a second frequency with each feed line having a uniquely controllable phase are provided separating adjacent cells in the matrix. By coupling an antenna element through a mixer to one row and column feed, a phase for each antenna element in the array can be uniquely controlled through a scan, thereby providing a simplified planar array to be implemented as a patch antenna.
