Abstract

ABSTRACTThis paper presents a novel design for a low-profile Fabry–Perot resonator antenna (FPRA) that operates at two distinct frequency bands using a single partially reflecting surface (PRS). The PRS is composed of two different types of unit cells arranged in a staggered fashion. These unit cells are comprised of double-sided complementary structures, including a square patch with a square aperture and a circular ring with a circular ring slot. To reduce the overall profile of the antenna, an artificial magnetic conductor (AMC) surface is utilized as the reflection plane. The proposed design employs a dual-band slotted patch antenna as the primary source. The overall dimensions of the FPRA are 91 mm×91 mm×5.54 mm. The performance of the prototype antenna is validated through measurement, demonstrating peak gains of 14.1 and 16.1 dBi at frequencies of 6.65 and 12.05 GHz, respectively. Additionally, the antenna exhibits −10 dB impedance bandwidths of 6.5–6.8 GHz and 12.15–12.23 GHz at the two frequency bands.KEYWORDS: Dual-bandFabry–Perotlow-profilepartially reflecting surface Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThe work was supported by the National Natural Science Foundation of China [62071282]; Open Foundation of China-Belarus Belt and Road Joint Laboratory on Electromagnetic Environment Effect [ZBKF2022020102].

单部分反射面双频低轮廓法布里-珀罗谐振器天线

摘要本文提出了一种新颖的低轮廓法布里-珀罗谐振器天线(FPRA)，该天线使用单个部分反射面(PRS)在两个不同的频段工作。PRS由两种不同类型的单位细胞组成，以交错的方式排列。这些单元格由双面互补结构组成，包括带有方形孔径的方形贴片和带有圆形环槽的圆形环。为了减小天线的整体轮廓，利用人工磁导体(AMC)表面作为反射面。提出的设计采用双频开槽贴片天线作为主源。FPRA的外形尺寸为91 mm×91 mm×5.54 mm。通过测量验证了原型天线的性能，在6.65 GHz和12.05 GHz频率下分别显示了14.1和16.1 dBi的峰值增益。此外，该天线在两个频段具有6.5-6.8 GHz和12.15-12.23 GHz的−10 dB阻抗带宽。关键词:双波段法布里-珀罗特-剖面部分反映表面披露声明作者未报告潜在的利益冲突。本研究得到国家自然科学基金资助[62071282];中白“一带一路”电磁环境效应联合实验室开放基金[ZBKF2022020102]。
