摘要

本文提出了一种1×4非对称y形狭缝加载微带阵列天线。该天线由矩形贴片和双层厚度的FR4衬底组成，贴片的四角处有四个不对称的y型缝隙。这种天线将在WLAN应用中得到最广泛的应用。提出了一种改进的阵列天线结构，以增强天线的辐射方向图和增益特性。天线阵元间距从λ/2减小到λ/3，提高了天线阵的辐射方向图调整能力。此外，天线阵中每个贴片上狭缝载荷的位置和大小可以调整，以获得良好的定向辐射方向图。利用IE3D软件对辐射方向图、反射系数量级的仿真结果进行了验证。仿真结果与实测结果吻合较好。因此，该天线阵列适用于多波段无线通信。

Investigated gain and radiation pattern of array antenna with asymmetric y-shaped slit loads MSA

This paper presents a 1×4 asymmetric Y-shaped slit loaded microstrip array antenna. The antenna consists of a rectangular patch with four asymmetric Y-shaped slits at the patch corners and a double thickness of FR4 substrate. This antenna will be most utilized in WLAN applications. A modified array antenna configuration is proposed radiation pattern and gain characteristics to enhancement. The radiation patterns adjusting of antenna array are improved by array element spacing from λ/2 down to λ/3. In addition, position and size of slit loads on each of some patches in antenna array can adjust for good directive radiation pattern. The simulation results of the radiation pattern, reflection coefficient magnitude are verified by IE3D software. Result good agreement between our simulation and the measurement. Consequently, this proposed antenna array is appropriate for multiband wireless communications.
