摘要

本文提出了一种矩形印刷单极天线，并进行了系统的研究，以提高天线的带宽。在减小衬底尺寸的情况下，采用了几种技术来获得印刷矩形单极天线的大阻抗带宽。通过适当优化槽尺寸和微带线馈线位置，可以增加阻抗带宽。简单的印刷矩形天线，没有槽位和偏移馈电，显示1.2:1 (1.94 GHz至2.30 GHz)和1.65:1(3.5 GHz至5.8 GHz)的阻抗带宽比，对于VSWR <;= 2的第一频段。然而，对于各种现有的带宽增强技术，带宽从0.36 GHz增加到3.82 GHz。方位面和仰角面的辐射方向图都比较好。

Improving bandwidth of printed rectangular monopole antenna

This paper proposes a rectangular printed monopole antenna where systematic study has been carried out to increase the bandwidth of the antenna. A few techniques are applied to obtain large impedance bandwidth for printed rectangular monopole antenna with reduced substrate size. With proper optimisation of slot dimensions and microstrip line feed position gives increased impedance bandwidth. Simple printed rectangular antenna, without slot and offset feed, shows 1.2:1 (1.94 GHz to 2.30 GHz) and 1.65:1(3.5 GHz to 5.8 GHz) impedance bandwidth ratio for VSWR <;= 2 for the first band. Whereas, for various presented band enhancing techniques, Bandwidth increases upto 3.82 GHz from 0.36 GHz. The radiation patterns in azimuthal and elevation planes are reasonably good.
