| 摘 要： | 简单介绍了平板圆片单极天线.提出了一种新型的组合单极天线形式,这种天线将四个圆片单极子垂直交叉放置,不仅依然能够在很宽的频带上满足反射损耗的要求,而且该天线具有较宽的波束和波束范围内有较好的圆极化性能等特点.对这种新型天线进行了分析,给出了天线的设计方法,研究了其超宽带性能,详尽讨论了天线的反射损耗、辐射方向图、轴比图,以及增益和群延时特性.分析结果验证了其在实现宽波束圆极化的同时具有良好的超宽带性能.这种新型小型化天线在无线通信、卫星通信和移动通信中具有良好的应用前景.

| Abstract: | A novel antenna is proposed.Four circular disc monopoles are placed across each other.The improved antenna is not only favorable for satisfying ultrawide-band return loss requirement but also advantageous in realizing the wide beams and good circular polarization performance within the beams.Analyses are conducted to determine the novel antennas' properties.The return loss,radiation patterns,axial ratio,gain and the time domain performance of the antennas are discussed detailedly.The analytic results verify... |
