| 摘 要： | 设计了一款基于PIFA结构的手机天线,以多支节和增加寄生单元方式实现天线的小型化和多频段要求。采用HFSS13.0高频电磁仿真软件对天线进行仿真优化,最终得到天线的尺寸为33 mm×13 mm×8 mm,同时天线在多个频点处谐振。仿真结果表明,谐振点位置S11≤-10 dB,天线和馈线匹配良好,天线带宽足够同时覆盖GSM850、DCS1800、PCS1900、LTE2300/2500、ISM/Bluetooth、WLAN(2.4GHz)工作频段。对设计天线进行了加工和实测,实测与仿真结果吻合良好,验证了本设计的可靠性。

| Abstract: | A mobile-phone antenna based on PIFA is designed, with way of multiple nodules and increasing parasitic elements to meet its requirements of miniaturization and multiple bands. The antenna is simulated and optimized with electromagnetic simulation software HFSS13.0 (High Frequency Structure Simulator),and the designed antenna is 33mm×13mm×8mm in size and resonates at multiple frequency points. Simulation results indicate that with parameter S11≤-10 dB,the proposed antenna could match well with feeder, and its bardwidth is enough to cover many operation frequency bands, including GSM850, DCS1800, PCS1900, LTE2300, LTE2300, ISM/Bluetooth and WLAN(2.4GHz).The proposed antenna is processed and measured, and the simulated results and measured results are quite idenical.All this eloquently verifies the reliability of this designed antenna. |
