摘要
本文针对下一代802.11ac无线局域网(WLAN)，进行了1×2圆形微带贴片天线(MPA)阵列的设计、仿真和优化研究。IEEE 802.11ac是一组MAC层增强功能，用于提高5GHz频段的吞吐量。这一新兴标准提供了更宽的信道、更高的吞吐量和更有效的频谱利用。利用Agilent ADS动量对所提出的天线阵列进行了设计和仿真。天线阵列采用FR4衬底(εr = 4.6, h = 1.6mm)设计。采用传输线模型计算了所提设计的尺寸。带四分之一波变压器的插入馈电用于馈电天线元件。提出的设计改进了经典矩形MPA的缺点。因此，1×2圆形贴片天线阵列的最大实现带宽和增益分别为292MHz和5.17dBi。所建议的阵列可以用作模板，以形成可用于下一代802.11ac wlan的更大阵列。
A 1×2 circular patch antenna array for next generation 802.11ac WLAN applications
In this paper, design, simulation and optimization study of a 1×2 circular microstrip patch antenna (MPA) array for next generation 802.11ac wireless LAN (WLAN) is presented. The IEEE 802.11ac is a set of MAC layer enhancements for higher throughput in the 5GHz band. This emerging standard provides wider channels, higher throughput and efficient use of spectrum. The proposed antenna array is designed and simulated using Agilent ADS momentum. The antenna array is designed using the FR4 substrate (εr = 4.6 and h = 1.6mm). The dimensions of the proposed design is calculated using the transmission-line model. An inset-feed with quarter-wave transformer is used to feed the antenna elements. The proposed design improves the shortcomings of a classical rectangular MPA. Hence, the maximum achieved bandwidth and gain of the 1×2 circular patch antenna array are 292MHz and 5.17dBi respectively. The proposed array may be used as a template to form larger arrays which can be used in next generation 802.11ac WLANs.
