| contents | In the recent years constructing time-invariant spatial-focusing beampatterns by using frequency diverse arrays (FDAs) is conveyed in several papers. Further than time-invariant spatial-focusing beampatterns, the unfeasibility of constructing range-dependent time-invariant beampatterns is demonstrated in this paper. It is indicated that the beampatterns produced by antenna arrays including FDAs are not independently controllable in time, t, and range, r, dimensions, in the farfield. Inappropriate applications of the FDAs having time-invariant spatial-focusing beampatterns in two recent papers are also discussed. |
