许多基于测量的研究表明，高方向性天线波束的自适应转向可以克服毫米波（mmW）频率下信号的较高路径损耗。在本文中，我们提出了一种新型的60 GHz方向图可重构天线能够转向其波束在方位角和仰角方向。这种可操纵天线的性能进行评估，通过射线跟踪模拟的城市城市模型。在视线（LOS）和非视线（NLOS）的情况下，建议的天线优于传统的全向天线的接收功率和延迟扩展特性。
A number of measurement based studies have demonstrated that adaptive steering of highly directional antenna beams can overcome higher path loss of signals at millimeter wave (mmW) frequencies. In this paper, we present a novel 60 GHz pattern reconfigurable antenna capable of steering its beams in both the azimuth and the elevation directions. The performance of this steerable antenna is evaluated via ray tracing simulations of an urban city model. In both the line of sight (LOS) and non line of sight (NLOS) scenarios, the proposed antenna outperforms a conventional omni-directional antenna in terms of received power and delay spread characteristics.
