摘　　要：文中提出并研究了一种以微带馈电的超宽带单极子天线,尺寸为42 mm×36 mm。天线印刷在相对介电常数为2.65,厚度为1 mm的介质板上,由辐射贴片及带矩形槽的接地平面组成。利用三维电磁仿真软件对天线的回波损耗、方向图等参数进行了仿真,其结果表明,该天线在2.5~16 GHz的频率范围内回波损耗〈-10 d B,具有超宽带的工作特性,且天线显示出较好的全向辐射特性,天线的结构简单、易于加工。A new design of microstrip-fed uhra-wideband antenna with the size of 42 mm × 36 mm is presented. The thickness of the substrate is 1 mm and the relative permittivity is 2.65. This antenna consists of a radiating patch and a grounding plane with a rectangular slot. The 3-D electromagnetic simulation software is applied to simulating the parameters such as return loss and radiation pattern of the antenna. Simulated results show that the antenna＇s frequency band range is 2.5 - 16 GHz,whose return loss is less than -10 dB, providing a wide usable bandwidth of 13.2 GHz. The antenna reveals a good omni-directional radiation characteristic . The configuration is simple, easy to fabricate and can be integrated into UWB systems.
