TitleOptimizing Uniformly Excited Linear Arrays through Time Modulation
Fondevila, J.; Bregains, J.C.; Ares, F.; Moreno, E. "Optimizing uniformly excited linear arrays through time modulation", IEEE Antennas and Wireless Propagation Letters, 38 - 40 Volume: 3, Issue: 1, Dec. 2004
[Abstract] The letter shows that, by the proper use of time modulation in equispaced linear arrays with uniform excitation distribution, it is possible to maintain the sidelobe zone of the radiated power below a certain - previously stipulated - level, whereas the undesired harmonics are minimized. In addition to that, the further extension of the technique to non-equispaced arrays permits a broadband response to be obtained, by simply searching the positions of the elements that reach the desired power pattern behavior within the required bandwidth.
