摘要
集成电路与微机械天线对于基底介质的要求不同 ,前者需要高介电常数的介质 ,而后者所需介质的介电常数则较低 ,要将两者集成到一起存在一定困难。为了满足蓝牙通信器件的需要 ,以便将微带天线与电路集成在一起 ,设计了背腔 -短接式微带贴片天线 ,并采用微机械加工工艺制作了样品 ,其 10dB带宽达到了 10 %以上 ,辐射效率为 6 7% ,长度仅为 1/6波长 ,基本达到了蓝牙通信器件的要求。
The substrate performances for integrated circuit and micromachined antenna are quite different in which the former requires high dielectric constant, but the latter doesn′t. Therefore it′s difficult to integrate circuits with microstrip antenna. To meet the needs of miniaturized Bluetooth devices, the paper presents a cavity shorted microstrip antenna manufactured by micromachining process. The 10dB bandwidth and efficiency of the micromachined Bluetooth antenna are more than 10% and 67%, respectively, and the length is only 1/6 wavelength. The antenna is suitable for Bluetooth devices.
