摘要
减少60ghz相控阵中天线单元的互耦是一个重要的问题,因为它直接影响端口阻抗和辐射方向图。本文提出了一种基于ebg的设计,采用波纹结构来减少两个天线单元之间的相互耦合,边沿距离为1.65 mm (0.33λ0)。在仿真中,使用高度为0.65 mm的波纹结构的隔离增强可达10.3 dB,并在57至66 GHz的频率上得到保证。以每层厚度为0.1 mm的LTCC工艺为限,选择波纹高度为0.7 mm的原型验证隔离增强效果,并给出了一致的实验和模拟结果。
Reduction of mutual coupling for compact 60-GHz cavity-backed antennas in LTCC
Reducing the mutual coupling of antenna elements in 60-GHz phased arrays is an important issue because it directly affects the port impedance and radiation patterns. This paper presents an EBG-based design using corrugated structures to reduce the mutual coupling between two antenna elements with an edge-to-edge distance of 1.65 mm (0.33λ0). Isolation enhancement using the corrugated structure with a height of 0.65 mm is up to 10.3 dB in simulation and is assured over the frequency of 57 to 66 GHz. Limited to the LTCC process with each layer of 0.1 mm height, the prototype of a corrugation height of 0.7 mm is chosen to verify the isolation enhancement and the agreed experimented and simulated results are shown.
