摘要：
This 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 under certain-previously stipulated-level whereas the undesired harmonics are minimized. In addition to that, the further extension of the technique to nonequispaced arrays permits to obtain broadband response, by simply searching the positions of the elements that reach to the desired power pattern behavior within the required bandwidth.
