摘要

提出了一种小尺寸、低轮廓的平面天线,用于集成蓝牙和超宽带(UWB)应用。该天线采用特殊微带线馈电,采用聚四氟乙烯(Er=2.4)基片,整体尺寸为20mm*46mm。散热元件的整体尺寸为15mm*16mm。在用于双带陷波的辐射贴片中嵌入半圆槽谐振器和裂环槽谐振器,以抑制WLAN干扰带。另外还耦合了一个矩形环形滤波器。该天线可在2.25 ~ 2.5GHz和3.0 ~ 10.75 ghz频率范围内工作,覆盖蓝牙(2.4 ~ 2.484 ghz)和超宽带(3.1 ~ 10.6 ghz),陷波频率为4.96 ~ 5.29 GH和5.54 ~ 6.01 ghz。

A small integrated bluetooth and UWB antenna with WLAN band-notched characteristic
A small-sized, low-profile, and planar antenna for integrated Bluetooth and ultrawideband (UWB) applications is presented with WLAN band-notched. The proposed antenna is fed by a special microstrip line and it is built on PTFE(Er=2.4) substrate with a whole size of 20mm*46mm. Besides, the overall size of the radiating element is 15mm*16mm. A semicircular slot resonator and a split ring slot resonator are embedded in the radiating patch for dual band-notched to reject the WLAN interference band. And a split rectangular ring filter also is coupled. The antenna can operate in the 2.25¿2.5GHz and 3.0-10.75GHz frequency range that cover the Bluetooth (2.4-2.484GHz) and UWB (3.1-10.6GHz) with band-notched of 4.96-5.29 GH and 5.54-6.01GHz results.
