| 摘 要： | 提出一种可应用在无线局域网系统中的双对称U型槽加载三频贴片天线。相对于单U型槽而言,加载对称U型槽所产生的频段具有更高的线极化纯度。以此为基础设计并制作出具有双对称U型槽结构的贴片天线。天线通过矩形贴片、外层对称U型槽以及内层对称U型槽3个结构的谐振实现2.4 GHz、5.2 GHz和5.8 GHz三频工作,3个频段的增益分别大于5.8 dB、4.8 dB和2.5 dB,各频段内交叉极化小于-20 dB,实测与仿真结果基本一致。

| Abstract: | In this paper, a tri-band patch antenna with double symmetric U-slot which can be used in the wireless local area network （WLAN） system is proposed. Through the analysis, compared with the single U-slot, the line polarization purity of the frequency band which is generated by symmetric U-slot is much higher. A patch antenna with double symmetric U-slot structure is designed and manufactured. The antenna operation frequencies of 2.4 GHz, 5.2 GHz and 5.8 GHz are realized by the square patch, the outer symmetric U-slot and the inner symmetric U-slot, and the gain is more than 5.8 dB, 4. 8dB and 2.5 dB, separately. The cross polarization of the antenna is less than - 20 dB within three bands. The measured results are similar to the simulated ones. |
