摘　　要：介绍了一种利用变形地板来展宽平面三角形单极子天线带宽的方法。通过在天线地板上刻蚀对称的变型L型缝隙,天线的阻抗带宽增加到2.5～10.8 GHz,带内驻波比(VSWR)<2。对比没有刻蚀缝隙的天线,不仅工作频带得到展宽,而且保持了较好的辐射性能。测量和仿真结果表明,天线的工作频带能够覆盖整个超宽带(UWB)范围。In this paper,a new design of planar triangular monopole antenna（PTMA for short） using a modified ground plane for bandwidth enhancement is proposed.By symmetrically etching a pair of modified L-shaped slots on the ground plane,the impendence bandwidth is increased to 2.5~10.8 GHz under the condition of VSWR2.Compared with the original antenna（not slotted）,the operating band of the proposed antenna is largely expended while good radiation characteristics are maintained.The measured and simulated results show that the operating band of the proposed antenna completely covers the frequency range of Ultra-Wide Band（UWB）.
