Abstract

A printed wide slot antenna fed by a novel feeding mechanism consisting of a printed bow tie feed placed within the slot aperture and metal baffles between the slot ground plane and a grounded back plane allow this antenna to operate over more than an octave bandwidth with a VSWR<2. Special features of the slot antenna design are its small slot ground plane (1/spl lambda//sub 0/ /spl times/1/spl lambda//sub 0/) and small back ground plane (2/spl lambda//sub 0//spl times/2/spl lambda//sub 0/). The cross polarisation level of the antenna lies between -22 dB and -36 dB, over the frequency range and the average gain of the antenna is 4.5 dBi.

用于PCN/UMTS应用的宽带天线

一种印刷宽狭缝天线由一种新型馈电机构馈电，该馈电机构由放置在狭缝孔径内的印刷领结馈电和狭缝接平面和接地后平面之间的金属挡板组成，允许该天线在超过一个倍频的带宽上工作，且VSWR<2。槽式天线设计的特点是其小槽式接地平面(1/spl lambda//sub 0//spl times/1/spl lambda//sub 0/)和小背景接地平面(2/spl lambda//sub 0//spl times/2/spl lambda//sub 0/)。在整个频率范围内，天线的交叉极化电平介于-22 dB和-36 dB之间，天线的平均增益为4.5 dBi。
