一种新型U型槽宽频微带天线

摘要

A new low-profile broadband microstrip antenna with slots is presented.U-slot loading technique is used to produce a new resonance point and broaden the impedance bandwidth.The antenna characteristics are analyzed and optimized numerically with Ansoft HFSS,and the simulation results show that there are two resonant frequencies of 12.83 GHz and 15.06 GHz.The relative bandwidth for ｜S11｜〈-10 dB can reach up to 940 MHz and 770 MHz%提出一种新型的低剖面宽带开槽微带天线。该天线通过U型槽加载,从而产生新的谐振点,达到展宽带的目的。采用HFSS软件对提出的天线模型进行仿真优化,结果显示,该天线在12.83 GHz、15.06 GHz两个频点产生谐振,天线阻抗带宽达到940 MHz和770 MHz
