摘　　要：提出并设计了一种带寄生单元宽带单极子天线,该天线由一个单极子天线附加两个寄生振子组成。仿真及实验结果证明:天线在保持单极子天线特性的同时,实现了其宽带特性。该天线在750～2240 MHz的频带内反射损耗小于-10 dB,具有水平全向的方向图、稳定的增益。天线的结构和电特性决定了天线有广阔的应用前景,非常适用于移动通信终端设备,作为手持终端天线和车载天线将大有可为。A novel wide-band monopole antenna with parasitic elements is proposed in this paper. Its structure and feeding method are both simple. Simulation and experiment result show that this novel antenna realize wide band without losing any other good characteristics. From 750 MHz to 2240 MHz, the return loss is less than -10 dB, and it has omnidirectional radiation pattern in horizon plane, stable gain. It is very suitable for wireless communication devices because of its structure and electric characteristics, and can be widely used as the portable terminal antenna and vehicle antenna.
