Hello,everyone. Usually I got the information of the patent antenna design from IEEE Antennas&Propagation magazin, and it gives me some new idea about the antenna design. But when I was reding Wong Kin-lu's planar antennas for wireless communications, I wanted to find information about the patent antenna design. I asked help to www.google.com, there's no. I asked help to my library, they told me you can refer to www.patent.gov.cn and www.uspto.gov, but there's still no. Could anybody tell me how to get the information about the patent antenna design.

1. S.N. Tsai,“Antenna module for partable computer," U.S. Patent No.6297779, Oct. 2,2001.
2. W.L. Cheng and C.H. Fang,"Antenna for portable device," U.S. Patent Application Publication No. US 2001/0040529

Thank you very much in advance.

Or, you can try h**p://www.freepatentsonline.com, introduce the patent number
6,297,779 then click "search" and you have access to the PDF file...
