Future intelligent, autonomous platforms (autonomous vehicles, robots, satellites, ships, air planes) and portable terminals are expected to have multiple functions such as wireless communication (with satellites and/or terrestrial base stations and/or ground terminals), ultra-fast data transfer, navigation, sensing, radars, imaging and wireless power transfer. These wireless systems operate at various frequencies. As a single radio frequency (RF) system usually has a narrow bandwidth, multiple RF systems at different frequency bands are often employed, leading to a huge increase in the volume, power consumption and cost. To address this need, it requires a single-aperture ultra-wideband (UWB) phased array capable of operating over an extremely wide range of frequencies, and having a low profile, wide-angle-scanning steerable beams, high gain, high efficiency and multiple polarizations (e.g. right-hand circular polarization for navigation, dual linear polarizations for mobile communication). Such an advanced antenna system does not exist yet. This project aims to tackle the ambitious challenges of addressing this need. This multi-disciplinary research consortium, having RF/microwave/mm-wave phased array researchers working together with researchers in optical beamforming and 3D printing, are ideally placed to development a new generation of low-profile UWB phased arrays, which is expected to find wide uses for both civilian and military applications.

未来的智能自主平台（自主车辆、机器人、卫星、船舶、飞机）和便携式终端预计将具有多种功能，例如无线通信（与卫星和/或地面基站和/或地面终端）、超快数据传输、导航、传感、雷达、成像和无线功率传输。这些无线系统以各种频率工作。由于单个射频（RF）系统通常具有窄带宽，因此经常采用不同频带的多个RF系统，导致体积、功耗和成本的巨大增加。为了解决这一需求，需要能够在极宽的频率范围上操作的单孔径超宽带（UWB）相控阵列，并且具有低轮廓、广角扫描可操纵波束、高增益、高效率和多个极化（例如，用于导航的右旋圆极化、用于移动的通信的双线极化）。目前还没有这样先进的天线系统。该项目旨在应对满足这一需求的雄心勃勃的挑战。这个多学科研究联盟拥有RF/微波/毫米波相控阵研究人员与光学波束成形和3D打印研究人员合作，非常适合开发新一代低轮廓UWB相控阵，预计将广泛用于民用和军用。
