中文摘要:
      提出一种由平面单极子天线及其寄生耦合枝节组成,应用于POS机的小型化全网通天线. 该天线的低频部分由E型枝节与短倒L型寄生枝节的耦合实现,天线的高频部分由直接馈电E型枝节、倒C型枝节、寄生单元实现,利用寄生枝节的多模谐振有效地拓展了高频段的带宽. 天线的总尺寸为61mm×30mm,实测S11小于-6dB的工作带宽分别为0.8~1.0GHz、1.45~2.90GHz,完全覆盖了GSM850/900/DCS1800/PCS1900/UMTS/LTE2300/LTE2500频段. 该天线结构简单、覆盖范围广、尺寸小,应用于相应POS机中能够获得良好的全向辐射功率(TRP)和全向接收灵敏度(TIS),具有很好的工程应用价值.
英文摘要:
      A miniaturized antenna of full netcom for POS terminal application is proposed. The antenna consists of planar monopole antenna and parasitic coupling stubs. The lower-frequency of the antenna is achieved by the coupling between E-shaped and short parasitic branch. The higher-frequency is accomplished by the fed E-shaped branch,inverted C-shaped branch and parasitic element,and the higher-frequency bandwidth is expanded effectively by using multimode microwave resonance of parasitic stubs. The total size of antenna is 61mm×30mm. The measured -6 dB impendence bandwidth of the antenna prototype is 0.8-1.0GHz,1.45-2.90GHz,which covers the bands of the GSM850/900/DCS1800/PCS1900/UMTS/LTE2300/LTE2500 compeletly. The antenna has merits of simple structure,wide frequency range and miniaturization.Meanwhile,it can obtain good total radiated power(TRP) and total isotropic sensitivity(TIS) performance for the specific POS terminal application,and gain the good value of engineering application.
