一种适用于GSM DCS和ISM频段的PIFA天线
内容简介：移动通信业务的多样化要求多种业务共用一副天线,以节省终端内的有限空间.在平面倒F天线(PIFA)的基础上加载一种新型的缝隙结构,得到一种适用于GSM900、DCS1800和ISM WLAN 2.4 GHz三个频段的小型宽带移动终端天线.仿真结果表明,该天线在三个频段上的相对阻抗带宽分别达到6.5%、7.5%和3.4%,尤其是在GSM 900 MHz频段的阻抗带宽比其他同类型天线展宽1倍.该天线具有较好的频率特性和辐射特性,完全适合多频移动通信终端应用.
Abstract：Diversified mobile communication service requires multi operations to share one antenna, in order to save limited space in the terminal. A compact microstrip antenna for triple-band of GSM900, DCS1800 and ISM WLAN 2.4 GHz was realized based on PIFA antenna with a novel slot structure. Simulation results showed that relative impedance bandwidths for the three bands were 6.5%, 7.5% and 3.4%, respectively. Especially, the impedance bandwidth of GSM 900 MHz was twice as wide as other antennas of the same kind. With excellent frequency and radiation characteristics, the antenna is very useful for multi-band mobile communication.
