本文提出了一种带有弯曲缝隙和不同接地金属通孔分布的贴片天线。采用弯曲槽来模拟双频工作，同时建议接地金属通孔的数量和位置以实现不同的辐射性能。对其特性进行了详细的分析，发现通孔的存在也改善了阻抗匹配。设计了四个样品，分别获得了双频线偏振、双频圆偏振和线偏振以及单频线偏振。最后制作了样品，测量结果与仿真结果吻合较好。
Patch antennas with a meandering slot and different distributions of grounded metallic vias are presented in this paper. The meandering slot is adopted to stimulate dual-band operation, while the number and position of the grounded metallic vias are suggested to achieve different radiation performances. The characteristics are analyzed in detail where we find that the existence of the vias also improves the impedance matching. Four samples are designed, where dual-band with both linear polarization, dual-band with circular- and linear-polarization, and single band with linear polarization are obtained, respectively. The samples are finally fabricated and the measurement results agree well with the simulation results.
