| 摘 要： | 针对蓝牙天线发展的要求,结合目前天线小型化技术,在研究平面倒F天线(PIFA)的基础上,采用曲流技术对PIFA天线进行了小型化设计。与同类型的PIFA天线相比,在相同工作频率(f0=2.45 GHz)的条件下,设计天线的回波损耗S11<-50 dB,相对带宽提高了0.7%,达到了3.7%,同时有效地缩小了天线的尺寸(11 mm×9 mm×6 mm)。对天线进行加工并测试,回波损耗为-10 dB的带宽为120 MHz,各项指标均满足蓝牙技术需要。

| Abstract: | In view of the development for Bluetooth antenna, combine with the antenna miniaturization technology, based on the study of Planar Inverted-F Antenna (PIFA), a miniaturized PIFA antenna with the meandering technology is designed in this paper. Compare with the same type of PIFA antenna, in the same condition of frequency (f0=2.45GHz), the return loss of the antenna S11<-50dB, relative bandwidth is 3.7% which increases by 0.7%. At the same time, whose size is 11mm×9mm×6mm, the size of the antenna is reduced effectively. The antenna is designed to be manufactured, the measured -10dB bandwidth is 120MHz, each character meets the needs of Bluetooth technology. |
