该文设计了一种低剖面、结构紧凑的平面倒F型三频手机天线，通过采用附加寄生单元增加天线的带宽，使天线完全覆盖GSM900、DCS1800和PCS1900频段，且增益大于0dB，满足无线通信系统对频段和带宽的要求。与传统的PIFA天线相比有更宽的带宽，在宽带通信系统中有较好的应用前景。

In this paper , a low-profile and compact PIFA antenna is presented .The antenna can produce wi-der frequency bandwidth by using an additional parasitic element .The antenna is fully covered GSM900, DCS1 800 and PCS1 900 bands.The gain of antenna is greater than 0dB, which meets the requirements of bandwidth in wireless communication systems .Compared with the conventional PIFA antenna , the antenna has a wider bandwidth , and has good application prospects in broadband communication system .
