摘要

提出了一种适用于平板电脑的小型单极天线，该天线与WWAN/LTE频段相匹配。在匹配网络的帮助下，天线的低频段和高频段的带宽都得到了拓宽。数值和实验结果表明，该天线满足6dB回波损耗对WWAN/LTE频段(670MHz ~ 980MHz/1650MHz ~ 2660MHz)阻抗带宽的要求。天线效率在低频段和高频段分别为48% ~ 69%和53% ~ 77%，峰值增益分别为1.28dBi和3.48dBi。所提出的天线的总尺寸为30×10mm2。介绍了该天线的细节，并对实验结果进行了讨论。

Small size antenna with a matching network for tablet computer application

A small size monopole antenna with a matching network for WWAN/LTE bands in the tablet computer is presented. With the aid of the matching network, the bandwidths of the antenna's lower and higher bands have been widened. The numerical and experimental results demonstrated that the proposed antenna satisfies the requirement of 6dB return loss for the impedance bandwidth of the WWAN/LTE bands (670MHz∼980MHz/1650MHz∼2660MHz). The antenna efficiencies are about 48%∼69% and 53%∼77% over the lower and higher bands with the peak gains of 1.28dBi and 3.48dBi, respectively. The total size of the presented antenna is of 30×10mm2. Details of the proposed antenna are described and the experimental results are discussed.
