摘要

蓝牙无线技术在工业、科学和医疗(ISM)无线电频谱频段提供短距离无线语音和数据通信。本文介绍了几种工作在2.45 GHz蓝牙频率下的偏置馈电半波印刷偶极子天线。采用了两种不同的进料技术，即侧进料和直接进料。为了减小天线尺寸，在某些结构中加入了直接馈电技术。为便于比较，还设计了在相同频率下工作的相应矩形贴片天线。利用micropatch和Sonnetlite软件对所设计的结构进行了数值模拟。天线已在GML层压板上制作并进行了测试。一个端口的测量结果表明，所有天线在相应的工作频率下匹配良好。共极化辐射模式显示出宽的波束宽度。

BIuetooth wireless technology low profile printed antenna

Bluetooth wireless technology provides short-range wireless voice and data communication in the industrial, scientific and medical (ISM) band of radio spectrum. This paper describes several half wave printed dipole antennas with offset feed operating at Bluetooth frequency of 2.45 GHz. Two variation of feeding techniques have been employed, namely the side feed and direct feed. Direct feed techniques were incorporated in some structures in order to reduce antennas size. A corresponding rectangular patch antenna operating at the same frequency is also designed for comparison purposes. Numerical simulations have been carried out on the designed structures using micropatch and Sonnetlite softwares. The antennas have been fabricated on GML laminates and tested. Measured one port results showed that all the antennas are well-matched at their corresponding frequency of operation. The co-polarisation radiation patterns exhibit broad beamwidths.
