 技術摘要 / Our Technology： |
本發明係一種超寬頻天線,其包括:一開槽部分,其係形成
於一印刷電路板之接地面,其具有一槽口;以及一共面波導饋入
部分,其具有一水平部及一垂直部,該水平部係與該垂直部垂直,
且該垂直部係置於該槽口中且可與一外接端子耦接。藉由上述結
構之超寬頻天線可接收3.1~10.6GHz之無線訊號,且其具體積小
及易於大量生產之優點,可降低其生產成本。此外,其亦可於該
共面波導饋入部分中加入寄生元件,以阻隔5~6GHz之無線區域網
路訊號。
The present invention relates to an ultra-wideband (UWB) antenna, which comprises: a rectangular aperture portion, formed from a ground plane of a printed circuit board and having an aperture; and a co-plane feeding structure, having a horizontal portion and a vertical portion, wherein the vertical portion is perpendicular to the horizontal portion, and the vertical portion is disposed in the aperture and connected with an external terminal. The ultra-wideband (UWB) antenna of the present invention can receive the wireless signal with 3.1˜10.6 GHz band, and have a very compact area (13 mm×23 mm) and is easy to be mass produced. Furthermore, a parasitism element can be added into the co-plane feeding structure, so as to reject the in-band interferences from the existing systems like 5˜6 GHz signals of wireless LAN.
