Antenna arrays are immensely powerful. The described design is a special case of a general phased array where the phase difference between elements is 0 degrees. With electronically controlled delays between elements, it is possible to make an electronically steerable antenna. The are lots of possibilities for using beam steering antennas, especially for power optimization.
- privong 11y ago> With electronically controlled delays between elements, it is possible to make an electronically steerable antenna. Multiple current and future radio telescopes are using this technique with dipole arrays at low frequencies, including LOFAR[0], the LWA[1], and eventually the SKA[2].
