First, let’s look at an intuitive example of steering a phased array beam. Figure 1 provides a simple illustration of a wavefront striking four antenna elements from two different directions. A …

In this letter, we study the enhanced multi-beam forming with a linear movable-antenna (MA) array by exploiting the new degrees of freedom (DoFs) via antennas’ position optimization.

Array beam forming techniques exist that can yield multiple, simultaneously available beams. The beams can be made to have high gain and low sidelobes, or controlled beamwidth. Adaptive …

2023年5月30日 · In this paper, we present a new approach permitting one to generate arbitrary structured array beams with shape-invariant characteristics, which can be done by simply …

然后我们可以通过频域的窗函数去控制它的beam pattern，最终的目的是表现出一种期望方向的信号很大，其他方向或者干扰方向信号为0或者尽可能小的一种情况。

2023年10月11日 · We show that by jointly optimizing the antenna positions vector (APV) and antenna weights vector (AWV) of a linear MA array, the full array gain can be achieved over …

2025年3月22日 · The effect of the obstacle size and position on the self-healing of the beam array is also analyzed by introducing the matrix correlation degree parameter K. The results verify …

5 天之前 · Phased array antennas have become a cornerstone in modern wireless communication, radar systems, and satellite technology. Unlike traditional antennas that rely …

In this review, we aim to investigate and discuss several challenges that hinder WABS for conventional PAAs, including the strong mutual coupling, narrow beamwidth of the element …

2021年8月12日 · This chapter deals with two topics that have much overlap, the multi-beam antenna (MBA) and the phased array (PA). MBAs were developed in the 1990s and 2000s to …
