Four-element antenna system for a clamshell phone

提出了一款用于翻盖手机中的四单元天线。该天线的阻抗带宽可以覆盖无线通信中的两个常用频段。在整个工作频段内的天线单元之间的互耦均小于-10分贝。参数分析给出了关键的结构参数对天线性能的影响。计算得到的相关系数和平均有效增益显示该天线系统能够提供很好的分集性能。

A novel compact four-element antenna system for a clamshell phone is presented. It has a wide-10 dB impedance bandwidth from 1870 MHz to 2560 MHz, covering both UMTS and 2.4 GHz WLAN bands. The mutual coupling of the antenna elements is below -10 dB in the working bands. The parameter analysis is presented to discuss the effects of the key dimension parameters. The calculated correlation coefficients and mean effective gains（MEGs） indicate that it has good diversity performance.
