| 摘 要： | 采用附加寄生单元的方式扩展频段,设计一种新型的PIFA三频手机天线。运用时域有限差分法(FDTD)计算该天线的回波损耗和方向图。仿真结果表明,天线在相应的三个工作频带(GSM900/DCS1800/ISM2450)内回波损耗S11<7.5dB(VSWR<2.5),增益大于0dB i,满足了无线通信系统对频段和带宽的要求。

| Abstract: | By adding the parasitic element to extend band,a new tri-band mobile phone PIFA antenna is designed.FDTD is used to calculate the return loss and pattern of the antenna.Simulation results show that the return loss of antenna(|S11|)in the corresponding three operating bands(GSM900/DCS1800/ISM2450) is more than 7.5dB(VSWR<2.5),and the gain is more than 0dBi.The antenna meets the requirements of the wireless communication system for frequency and bandwidth. |
