摘要
介绍了一种可工作在3～11．4GHz的超宽带平面天线，采用了一级阻抗变换和在接地板上附加梳型槽等方法来展宽天线的带宽，在带宽内方向图基本全向，最小增益为2dB，最大为5．5dB，体积小、剖面低易于集成，完全适合超宽带通讯系统的需要，具有较高的实用价值。
An uhra-wideband （UWB） planar antenna operating at 3GHz- 11.4GHz is introduced; by adopting first-order impedance transformation and comb-type slots on grounding plate, the bandwidth of the antenna is stretched, basic omnidirectional antenna pattern in the bandwidth is obtained, and the minimum and maximum gains are 2dB and 5.5dB respectively. The antenna features small-size and easy integration due to low profile; it fully meets the requirements of the UWB communication systems, and has high applicable value.
