摘要
为了在同一副天线上实现定向和全向方向图,提出了一种方向图可重构印刷振子天线。通过控制开关的状态,天线实现单极子和带反射器的偶极子两种工作方式,分别实现全向和定向方向图。用Ansoft HFSS软件对天线尺寸进行了分析和优化。根据仿真结果对于所提出的天线进行了制作和测试,并给出了测试结果。测试结果表明:开关断开时,天线带宽为2.09～2.44GHz;开关闭合时,天线带宽为2.64～2.94GHz。
In order to obtain directional pattern and omnidirectional pattern in one antenna,a printed dipole antenna with reconfigurable radiation pattern is proposed in this paper. By controlling the states of the switches,the antenna can be operated as a monopole antenna with omnidirectional pattern or a dipole antenna with reflector of directional pattern. The effects of the antenna dimensions on the antenna performance are analyzed using a commercial software package called Ansoft HFSS,and then the optimized para...
