摘要
设计了一种加载U型缝的小型化分形结构微带天线。该天线应用Giuseppe Peano分形理论和U型缝加载技术,延长电流的有效路径,从而降低天线的谐振频率,实现天线小型化,同时采用空气作为介质层,减小天线的Q值,增加天线带宽。通过使用HFSS对天线进行仿真优化,得到了天线尺寸参数。仿真结果表明,天线的相对带宽为6%(3.47~3.71GHz),最大增益可达2.91dBi,整体辐射性能良好。天线贴片尺寸仅为14mm×14mm,相比于普通微带天线,面积缩减了59%。该天线结构简单,尺寸小,能较好地适用于WiMAX通信。
A miniaturized fractal microstrip antenna with U -shaped slot was designed. The antenna realized miniaturization by applying Giuseppe Peano fractal technique and U-shaped slot. At the same time, air dielectric layer was introduced to reduce the Q value and improve bandwidth. The structure parameters of the antenna were simulated and optimized by the HFSS software. The simulated results show that the frequency channels of the antenna are within 3. 47-3. 71 GHz, and the relative bandwidth of the antenna is 6%. The peak gain of the antenna is 2. 91 dBi. The patch size of the proposed antenna is only 14 mm×14 mm and the area of the proposed one is reduced about 59% from the common antenna. Moreover, the antenna has a simple structure and a small size, which could be applied to WiMAX communication.
