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。
In view of the development for Bluetooth antenna, combining with the antenna miniaturization technology, based on the study of Planar In- verted-F Antenna （PIFA）, a miniaturized PIFA antenna with the meandering technology is designed in this paper. Compared with the same type of P｜FA antenna, in the same condition of frequency 0c0 = 2.45 GHz）, the return loss of the antenna S i i is less than-50 dB, relative bandwidth is 3.7% which increases by 0.7%. At the same time, the size of the antenna（ 11 mm ~ 9 mmx 6 mm） is reduced effectively. The antenna is designed to be manufac- tured, the measured -lO dB bandwidth is 120 MHz, each character meets the needs of Bluetooth technology.
