A weighted thinned linear array synthesis technique is analyzed and some interesting conclusions have been made. A linear array composed of eight pattern reconfigurable antenna elements is manufactured to demonstrate the excellent performance of the array. The active element pattern of each element is ...
between array elements by using an embedded pattern technique. The example models an array two ways: (1) using the pattern of the isolated element or (2) using the embedded element pattern, and then compares both with the full-wave Method of Moments (MoM)-based solution of the array. ...

With a phased array, you can electronically steer that pattern without having to physically move the array simply by adjusting the phase of the signals to each individual element. Commonly, an array is made up of antennas, which is similar in a way to how wireless communication and radar are...
elementcan be individually adjusted. By synthesizing an appropriate phase distribution the array pattern can be steered towards specific directions. Although this structure adds complexity to the feeding network, the potential reconfiguration capabilities are enhanced and a better control of the radiation ...
