摘 要: 超宽带天线(UWB)在短距离无线通信中的研究、设计逐渐成为热点。本文使用微带对阶梯缝隙进行馈电,同时在该阶梯缝隙下方再增加一条缝隙,改善天线的低频段阻抗匹配,得到一种改进的微带馈电阶梯缝隙UWB天线。测量结果显示,该天线的dB(S11)参数在2.9GHz-11.2GHz内小于-10dB,其相对带宽为117.7%。 UWB antennas become a hot spot in the application of short distance wireless communication research and design. A micro-strip fed UWB antenna of tapered slot is proposed in this paper. Another line slot is added under the tapered slot to improve the impedance matching characteristics. The measurement results of the antenna show that the dB(S11) parameter is less than -10dB from 2.9GHz to 11.2GHz, with the relative bandwidth of 117.7%.
