| 摘 要： | 提出了一种具有陷波特性的多用途小型超宽带微带天线。该天线类似一般的宽缝隙微带天线,但在矩形调谐支节内嵌入T形支节获得了陷波特性。通过数值仿真和实验测量,对天线的阻抗特性、方向图和增益进行了研究。结果显示该天线在2.39～12GHz的频段内驻波比小于2,其中的5.15～5.95GHz的范围内具有陷波特性。同时该天线还可覆盖2.4GHz无线局域网(WLAN)频段,在整个工作频段内有良好的辐射方向特性。

| Abstract: | A compact frequency notched microstrip slot antenna for multiple application was proposed. The antenna was similar to a conventional microstrip slot antenna. To achieve frequency notched characteristic, a cross wide slot and a rectangular stub with a T shaped stub embedded it were employed. It had been studied both numerically and experimen-tally for its impedance bandwidth, radiation patterns and gain. As will be seen, an operation bandwidth from 2.39 to 12GHz for stand wave ratio lower than 2, in which a frequency notched band from 5.15 to 5.95 GHz, has been achieved. The antenna can also be used for 2.4GHz WLAN application. Good radiation performance over the entire fre-quency range has also been achieved. |
