提出一种新型的微带馈电准自补天线，其辐射贴片由矩形和扇形金属片构成，并在地板上刻与辐射元互补的缝，天线整体尺寸为25 mm×32 mm×1 mm，为进一步展宽带宽，在馈电点下方的地板上挖去一个矩形缺口。仿真结果表明：驻波比小于2的带宽覆盖3.04~11.00 GHz，在整个工作频段有良好的辐射方向图。通过在馈线上嵌入U型槽，实现了对WLAN频段的陷波，而通带内仍可保持稳定的增益。

A novel microstrip-fed quasi-self-complementary antenna was proposed. This antenna with overall size of 25 mm×32 mm×1 mm consists of a rectangular and a fan-shaped radiating metal patches, and its counterpart slot was etched on the other side of the dielectric substrate. In order to broaden bandwidth, there was a rectangular notch on the ground plane. The results of simulation show that the VSWR is less than 2 over the frequency range of 3.04-11.00 GHz. The antenna exhibits very stable radiation patterns over the entire operating bandwidth. An U-shaped slot is embedded into the feed line to obtain the band-notched characteristic in the frequency band of WLAN, meanwhile the gain of the band-notched antenna is stable in pass band.
