| 摘 要： | 给出一种工作于900MHz的共面波导(CPW)馈电单极子天线的设计。该单极子天线以共面波导的中心导带为辐射单极子，以中心导带两边的金属导体作反射板，结构简单紧凑。但是由于天线与共面波导之间缺少有效的隔离，造成天线性能受共面波导尺寸的影响较严重。本文通过模拟计算和实验测量详细分析了共面波导尺寸的变化对天线性能的影响，给出了结合共面波导尺寸设计的工作在900MHz的单极子天线结构数据。

| Abstract: | A monopole antenna fed with a coplanar waveguide (CPW) operating at 900MHz is pr esented in the paper, in which the central conductor strip of the CPW is used as the monopole to transmit power and the conductor ground of the CPW is used as a reflector. The monopole antenna has a very simple and compact configuration. Ho wever, the dimension of the CPW impacts strongly on the performance of the anten na because they are not in effective isolation. The antenna fed by a CPW with di fferent dimensions is investigated numerically and experimentally. And the desig n of the antenna with a given dimension of a CPW operating at 900 MHz is demonst rated. |
