dual ISM-band application is proposed. The proposed antenna, including WSS(Bm|B  
a small ground plane, occupies a volume of 2023.70.8 mm3 \QiqcD9Y  
(FR-4). The impedance bandwidth with 10 dB return loss is about a}w&dE$!-  
150 MHz (2380–2530 MHz) for 2.4 GHz band and 1450 MHz (5130– GBW 7Y  
6580 MHz) for 5 GHz band. The measured radiation patterns are M&OsRrq  
approximately omnidirectional and yield a gain of 1.0 d .. X

我需要一篇比较短的完成学位英语之用！ =\*S'Ded  
如果我不用回复能下就好了

谢谢楼主分享

現工作需要了解一些這方面的設計參考..........

拿來參考一下

何必非要设置答复呢，有点浪费论坛空间 u+_#qk0NfK  
还是支持LZ的贡献精神 wah`
