Abstract

Recent advancements in 5G/millimeter-wave (mmWave) technologies have led to the development of next- generation IoT devices that provide large-scale connectivity and high data rates. To ensure reliable communication and consistent performance, these devices must have wide angular coverage and high detectability, allowing them to maintain stable connectivity regardless of their orientation or positioning. In this work, we introduced a 3-D lens-enabled semipassive millimeter-wave identification (mmID) for next-generation Internet-of-Things (IoT) systems, capable of quasi-planar angular coverage and ultra-long range capabilities. The system employs a concave meniscus dielectric lens combined with a Rotman-lens-based mmID, achieving a peak differential radar cross section of −15.1 dBsm and near-planar 3 dB angular coverage of

$\pm$

${\text{85}}^{\circ }$

. Using a proof-of-concept frequency-modulated continuous wave (FMCW) radar, the mmID demonstrated detection at an ultra-long range of 68 m at incident angles of

${\text{15}}^{\circ }$

and

${\text{85}}^{\circ }$

, with an average localization error of 4 cm. Furthermore, utilizing the maximum allowable 75 dBm equivalent isotropic radiated power in 5G applications, the proposed system has a projected theoretical maximum range of 1.3 km and 1.02 km at incident angles of 15

$^{\circ }$

and 85

$^{\circ }$

, respectively, making it a promising solution for next-generation orientation-agnostic IoT applications.

实现准平面覆盖：用于超远程物联网应用的凹半月板透镜增强的基于rotman透镜的中间件

5G/毫米波（mmWave）技术的最新进展推动了下一代物联网设备的发展，这些设备可提供大规模连接和高数据速率。为了确保可靠的通信和一致的性能，这些设备必须具有广角覆盖和高可探测性，无论其方向或定位如何，都能保持稳定的连接。在这项工作中，我们为下一代物联网（IoT）系统引入了一种启用3d透镜的半无源毫米波识别（mmID），能够实现准平面角度覆盖和超远距离功能。该系统采用凹半月板介质透镜与基于rotman透镜的mmID相结合，实现了- 15.1 dBsm的峰值差分雷达横截面和$\pm$${\text{85}}^{\circ}$的近平面3db角覆盖。使用概念验证型调频连续波（FMCW）雷达，mmID演示了在${\text b{15}}^{\circ}$和${\text{85}}^{\circ}$入射角下在68米的超远距离上的探测，平均定位误差为4厘米。此外，利用5G应用中允许的最大75 dBm等效各向同性辐射功率，所提出的系统在入射角分别为15$^{\circ}$和85$^{\circ}$时的预计理论最大距离分别为1.3 km和1.02 km，使其成为下一代方向不可知物联网应用的有希望的解决方案。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
