摘要:
提出一种简单结构紧凑的方向图可重构天线.该天线由3条微带线和介质基板组成,微带线印在基板的顶部.将PIN二极管集成在左、右两侧的微带线上,通过二极管开关的导通和断开,使天线在yoz平面获得2种定向与全向的辐射方向图.对天线进行仿真、制作和测试.实验结果表明:阻抗带宽可达14.7%,定向最小增益1.2 dBi,全向最小增益1.7 dBi;该天线在2.19~2.54 GHz频段上有较好的定向性和全向性,适用于抗干扰能力要求较高的无线通信系统.
Abstract:
A simple compact planar pattern reconfigurable antenna is proposed. The antenna consists of three microstrip lines and dielectric substrates, the microstrip are printed on the top layers of the substrate, respectively. PIN diodes are integrated on the microstrip lines on the left and right sides so that the antenna can obtain two directional and omnidirectional radiative direction patterns in the yoz plane by switching the ON/OFF states of the diodes. The antenna is simulated, fabricated and measured. Experimental results indicate that the antenna achieves a impedance bandwidth of 14.7%. The measured orientation minimum gain is 1.2 dBi and the measured omnidirectional minimum gain is 1.7 dBi. The antenna has good directivity and omnidirectionality in 2.19-2.54 GHz band, which is suitable for wireless communication systems with high anti-interference capability requirements.
