Abstract

To address the specific requirements of antennas in Unmanned Aerial Vehicle (UAV) joint radar-communication (RadCom) systems, a novel low-profile reconfigurable metantenna with the capability of frequency and pattern reconfiguration is proposed in this paper. The proposed antenna consists of a metasurface layer with 3 × 3 square unit cells and a simple feeding network with two pairs of PIN diodes. Specifically, the designed metantenna has a low profile of 0.064 λ₀ (λ₀ is the free space wavelength at 5.5 GHz). And measured results show that, for the broadside radiation mode, the −10 dB operating bandwidth is about 12.1 %, ranging from 5.05 to 5.7 GHz with a maximum gain of 8.9 dBi. For the conical radiation mode, the −10 dB operating bandwidth is about 21.9 %, ranging from 5.88 to 7.33 GHz with a maximum gain of 6.83 dBi. Given its excellent radiation performance, the metantenna designed for UAV joint RadCom systems holds significant research significance and value in the field of multifunctional reconfigurable antennas.

用于无人机联合 RadCom 系统的低矮型频率和模式可重构元天线

为满足无人飞行器（UAV）联合雷达通信（RadCom）系统对天线的特殊要求，本文提出了一种新型低剖面可重构元天线，具有频率和模式重构能力。拟议的天线由一个具有 3 × 3 正方形单元格的元面层和一个具有两对 PIN 二极管的简单馈电网络组成。具体来说，所设计的元天线具有 0.064 λ（λ 为 5.5 GHz 时的自由空间波长）的低剖面。测量结果表明，对于宽边辐射模式，-10 dB 工作带宽约为 12.1%，频率范围为 5.05 至 5.7 GHz，最大增益为 8.9 dBi。在锥形辐射模式下，-10 dB 工作带宽约为 21.9%，频率范围为 5.88 至 7.33 GHz，最大增益为 6.83 dBi。鉴于其出色的辐射性能，为无人机联合 RadCom 系统设计的元天线在多功能可重构天线领域具有重要的研究意义和价值。
