摘　　要：设计了3种微带线馈电的宽缝结构的超宽带天线:矩形微带馈电的阶梯状宽缝天线,矩形微带馈电的半圆形宽缝天线和圆形微带馈电的半圆形宽缝天线。实测结果表明这3种天线都具有超宽带性能。其中具有圆形微带馈电的半圆形宽缝天线具有更宽的阻抗带宽和良好的辐射性能。Three different ultra-wideband antennas are presented in this paper： a rectangular microstrip patch and a step cut on the ground of the microstrip-line, a rectangular microstrip patch and a semicircular cut on the ground of the microstrip-line; a circular microstrip patch and a semicircular cut on the ground of the microstrip-line. The measured results show that all the antennas have properties of ultra-wide bandwidth. The antenna which has a circular microstrip patch and a semicircular cut on the ground of the microstrip-line has much more wide bandwidth than the others and has stable radiation patterns over its whole frequency band.
