摘要

本文提出了一种谐振频率为1.59 GHz和3.65GHz的可重构CPW馈源天线。通过开/关嵌入天线的PIN二极管开关来进行重新配置，以修改散热器的电流路径。当开关打开时，天线谐振频率为1.59 GHz，当开关关闭时，天线谐振频率为1.55 GHz和3.65 GHz。本文分析了该天线在两个频率下的电流分布和功能。采用CPW馈电技术，通过调整辐射体与地之间的间隙，实现了阻抗的变化，得到了良好的匹配效果。给出了反射系数、电流分布、增益和辐射方向图的仿真结果。

CPW Fed Frequency Reconfigurable Dual Band Antenna Using PIN Diode

The article presents a frequency reconfigurable CPW feed antenna resonating at 1.59 GHz and 3.65GHz. Reconfiguration is carried out through switching on/off the PIN diode switch embedded with the antenna for modifying the current path of the radiator. As the switch is turned on, antenna resonates at 1.59 GHz and when the switch is turned off, antenna offers dual-band resonating at 1.55 GHz and 3.65 GHz. The paper has analyzed the current distribution and the functioning of the antenna at both the frequency. Using CPW feeding technique, by adjusting the gap between radiator and ground we have varied the impedance and got excellent matching. Simulated results of the reflection coefficient, current distribution, gain, and radiation pattern are presented.
