摘要

本文介绍了用于便携式收发器的多波段天线的各种小型化技术。考虑的技术包括折叠、弯曲和包裹主散热器。此外,还描述了利用地槽拓宽现有频带或产生新频带的方法。这些技术通过设计实例加以说明。最后,提出了一种由四分之一椭圆单极子和四分之一椭圆带互补槽的天线组成的宽带天线。这些天线覆盖了850MHz至6GHz频谱中所有流行的无线频段,相对于6dB回波损耗参考。给出了这些小型多波段天线的全波电磁仿真和实验结果。

Miniaturization techniques of multiband antennas for portable transceivers
This paper describes various miniaturization techniques of multiband antennas for portable transceivers. The considered techniques include folding, meandering and wrapping of the primary radiator. In addition, utilization of ground slots to widen the existing or generate new bands is described. These techniques are illustrated through design examples. Finally, a wideband antenna created by wrapping a quarter-elliptical monopole and a quarter-elliptical antenna with a complimentary slot are presented. These antennas cover all the popular wireless frequency bands in the 850MHz to 6GHz frequency spectrum with respect to the 6dB return loss reference. Full-wave EM simulations and experimental results for these compact multiband antennas are given.
