提出了一种适用于超宽带（UWB）应用的小型超宽带天线，该天线具有四个L形圆形贴片和一个圆形缝隙。接地层也被修改为对角边缘，矩形槽和I形槽。结果表明，辐射体的L形和圆形切口提高了天线的带宽。通过切割矩形槽和在顶角处截断接地，进一步提高了带宽。该天线工作频率为2.63 ~ 12.1GHz。通过仿真和实测结果对结果进行了验证。在3.3 GHz、7.0 GHz和9.2 GHz谐振频率下，反射系数分别为-30.38 dB、29.13 dB和-40.25 dB。所提出的天线提供了比FCC标准宽26.26%的带宽。
This article presents a compact size UWB antenna with circular patch containing four L-shape and a circular slot for ultra wide-band (UWB) applications. Ground plane is also modified with diagonal edges, rectangular slot and I-shaped slots. It has found that the L-shape and circular cut on radiator improves the bandwidth of antenna. Bandwidth is further improved by cutting rectangular slots and truncated ground at top corners. The proposed antenna operates from 2.63 GHz to12.1GHz. Results are validated through simulations and measured results. Reflection coefficients of −30.38 dB,29.13dB and −40.25 dB for the 3.3 GHz, 7.0 GHz and 9.2 GHz resonant frequencies respectively are achieved. The proposed antenna provides a 26.26% wider bandwidth than FCC standard.
