| 摘 要： | 基于宽带紧凑耦合技术，提出一款小尺寸多频段工作的平面印刷手机天线。天线主要由驱动单元、耦合单元和分支单元3部分组成。耦合单元和分支单元分别在低频产生谐振，控制低频段工作带宽，而驱动单元主要控制高频段工作带宽。通过仿真优化天线参数，制作了上述天线的实验模型，并进行严格测试。测试结果与软件仿真基本吻合，达到设计要求。该天线能够工作在CDMA800／GSM1800／1900／UMTS以及LTE2300／2500等多种无线通信频段，具有一定通用性。

| Abstract: | Based on broadband compact coupling technology, this paper presents a small-size planar printed mobile phone antenna with multi-band operations. The proposed antenna is composed of the driving unit, the coupling unit and the branch unit. The coupling unit and the branch unit produce resonance at low frequencies section respectively, controlling the low frequency operating bandwidth simultaneously, and the high frequency drive unit mainly controls operating band-width. The author made the experiment model of the aforesaid antenna by simulating optimized antenna parameters and conducted tests carefully. The measured results is basically consistent with the software simulation results to achieve the design requirements. The proposed antenna can work under multi-frequency bands, such as CDMA800 /GSM1800 /1900 /UMTS and LTE2300 /2500, which has a certain commonality. |
