摘要
本文设计、制作了一种紧凑、高增益、高效率的8×2元件微带贴片天线阵列,并对其进行了表征。采用薄陶瓷衬底(εr = 9.9, h = 127 μm)和基于四分之一波阻抗匹配的插入馈电技术,优化阵列结构,使其工作在60 GHz频段。采用是德科技的高级设计系统软件(ADS)进行设计仿真。该阵列结构在增益(16.8 dB)、指向性(17.9 dB)和辐射效率(77.43%)方面表现出优异的性能。因此,它完全满足了近距离室内无线应用的要求,可以作为毫米波射频前端集成电路的合适候选者。
A compact, high gain and high efficiency 8×2 patch antenna array for 60 GHz communication systems
In this paper, a compact, high-gain and high-efficiency 8×2 elements microstrip patch antenna array has been designed, fabricated, and characterized. The proposed array configuration was optimized to operate at 60 GHz frequency band, using as a material, a thin ceramic substrate (εr = 9.9 and h = 127 μm) and, as a technique, the inset-feed based on quarter-wave impedance matching method. Design simulation has been performed by using Advanced Design System Software (ADS) from Keysight Technologies. The proposed array structure exhibits excellent performances in terms of gain (16.8 dB), directivity (17.9 dB), and radiation efficiency (77.43%). It therefore meets perfectly the requirement for short-range indoor wireless applications, and it can be a suitable candidate for the millimeter wave RF front-end integrated circuits.
