ABSTRACT

This work focuses on designing a low-profile frequency selective surface transmitarray antenna at 12 GHz using a four-layer Split Ring Resonator structure. The parametric analysis shows a high transmission coefficient magnitude of −2.38 dB and 349-degrees phase range. X-band horn antenna is used as a feed source to illuminate the Frequency Selective Surface (FSS) transmitarray layers. Each FSS layer is comprised of 121 elements. The measured results show a wide impedance bandwidth of 35%, a high gain value of 21.9 dBi and 11.6% 1-dB bandwidth. The proposed design can be used in high gain array antenna applications, particularly Ku band Satellite communication systems.

一种用于Ku波段卫星通信的高增益紧凑型发射阵列天线

摘要

这项工作的重点是使用四层裂环谐振器结构设计 12 GHz 的低剖面频率选择性表面发射阵列天线。参数分析显示 -2.38 dB 的高传输系数幅度和 349 度相位范围。X 波段喇叭天线用作馈源以照亮频率选择表面 (FSS) 发射阵列层。每个 FSS 层由 121 个元素组成。测量结果显示,35% 的宽阻抗带宽、21.9 dBi 的高增益值和 11.6% 1-dB 带宽。所提出的设计可用于高增益阵列天线应用,特别是 Ku 波段卫星通信系统。
