| 摘 要： | 提出一种适用于蓝牙频段的小型化全向天线。该天线采用低温共烧陶瓷(LTCC)技术,将金属导线按曲折走线的方式内埋于LTCC微波陶瓷介质中,上下层导线通过通孔实现互连,有效缩小了体积,并保护了天线辐射单元以提高可靠性。通过分析天线三维结构,提取了天线等效电路模型,电磁场仿真与电路仿真结果基本一致。与传统天线相比,该天线具有全向性好、带宽大、性能稳定等优点,且外形短小紧凑,适用于对天线尺度要求比较苛刻的各种高灵敏度、低剖面的无线通信收发模块及移动通信终端。

| Abstract: | A compact omni-directional antenna for bluetooth application is proposed in this paper. Based on the Low Temperatue Co-fired Ceramic (LTCC) technology, the strip meander conductor lines with connecting vias are embedded in the multilayer microwave ceramic to achieve a compact and reliable structure,and based on which an equivalent circuit model is presented. The circuit simulation results are similar to the electromagnetic (EM) full wave simulation. This proposed structural model is validated through actual LTCC process. Measured results show good performance and agree well with the high frequency EM simulation. The broadband omni-directional chip antenna is very small with a size of only 6.0 mm×2.0 mm×1.2 mm. Compared with the conventional antenna, the compact omni-directional antenna is suitable for mobile communication modules and handsets which limit the antenna size. |
