Abstract

A compact wideband slotted hexagonal patch antenna (CWSHPA) with a modified ground plane structure for WiFi-5/6 communication has been designed and proposed in this paper. In the hexagonal patch antenna, a substrate material named Rogers RT5880 with a thickness of 0.79 mm is used. The modified ground plane structure has a good impact on the antenna size reduction as well as the performance improvement of the antenna. The optimized volume of the antenna is 34×20×0.79 mm3 (537.2mm3) which covers the frequency range of 5.1697 – 7.5388 GHz under the −10 dB scale. It also shows that the radiation efficiency ranges from 79.19% to 89.37% and the efficiency is 83.03% at 6. 33 GHz. The average radiation efficiency within the operating band is about 85%. The gain and the directivity are varying from 3.1 dB to 4.1 dB and 3.6 to 4.9 dBi. The proposed microstrip patch antenna exhibits a gain of 3.995 dB at centre frequency of 6.33 GHz which gives the Omni-directional radiation pattern as well as a competitor of WiFi-5/6 communication. The designed slotted hexagonal microstrip patch antenna (MPA) is simulated by using the CST microwave studio suite 2018.

一种适用于WiFi-5/6通信的小型宽带开槽六角贴片天线和改进的接地结构

本文设计并提出了一种适用于WiFi-5/6通信的紧凑型宽带开槽六角贴片天线(CWSHPA)。在六边形贴片天线中，衬底材料名为Rogers RT5880，厚度为0.79 mm。改进的地平面结构对减小天线尺寸和提高天线性能有很好的影响。优化后的天线体积为34×20×0.79 mm3 (537.2mm3)，在−10 dB范围内覆盖5.1697 ~ 7.5388 GHz的频率范围。辐射效率范围为79.19% ~ 89.37%，6时效率为83.03%。33 GHz。工作波段内的平均辐射效率约为85%。增益和指向性在3.1 ~ 4.1 dB和3.6 ~ 4.9 dBi之间变化。该微带贴片天线在中心频率为6.33 GHz时的增益为3.995 dB，具有全向辐射方向图，可与wi - fi 5/6通信相媲美。利用CST微波工作室套件2018对设计的开槽六边形微带贴片天线(MPA)进行了仿真。
