Abstract

A new AMC based broadband low-profile antenna is presented. The proposed antenna is composed by a patch, finite AMC cells and a slotted ground plane, and fed by a microstrip line under the ground plane. The structure of the proposed antenna is simple and compact, which can be realized by a three-layer printed circuit board (PCB) substrate. To verify the performance of the new AMC antenna, a reference patch antenna with the same thickness and feeding method is used for comparison. The new AMC antenna realizes a wide impedance bandwidth of 23% and a high gain up to 8.75dBi with an overall size of 1λ0×1λ0×0.047λ0 (λ0 is the free space wavelength at 28GHz). In addition, it solves the inherent disadvantage of backward radiation induced by aperture coupling while utilizes the advantage of low cross polarization property. The good performance suggests that the proposed novel AMC antenna is fully capable for 5G mm-wave AiP application.
面向5G毫米波AiP应用的新型低姿态高性能AMC天线研究
提出了一种新的基于AMC的宽带低姿态天线。该天线由贴片、有限AMC单元和开槽接平面组成,并由接平面下的微带线馈电。该天线结构简单紧凑,可通过三层印刷电路板(PCB)衬底实现。为了验证新型AMC天线的性能,采用相同厚度和馈电方式的参考贴片天线进行比较。新型AMC天线实现了23%的宽阻抗带宽和高达8.75dBi的高增益,总体尺寸为1λ0×1λ0×0.047λ0 (λ0为28GHz自由空间波长)。此外,它在利用低交叉极化特性的同时,还解决了由孔径耦合引起的反向辐射的固有缺点。良好的性能表明,该新型AMC天线完全能够满足5G毫米波AiP应用。
