摘要:
根据紧耦合能够有效拓展天线工作带宽的原理,结合天线在强耦合安装环境下阻抗的变化规律,研究贴片与金属地对天线阻抗的影响,提出了一种能够嵌入金属机箱的超宽带共形天线。通过仿真技术表明:该天线在0.8~3.2 GHz 频段范围内的S11 均小于-10 dB,且天线增益大于3 dBi。可见,设计的天线能够满足列车无线通信系统对宽频带和共形的性能需求。
Abstract:
Base on the theory that tightly coupling can extend the bandwidth of the antenna, the rule in variations of antenna impedance in the strong coupled environment was used to study the influence of patch and metal ground on the impedance of the designed antenna. A new tightly coupled ultra-wideband internal conformal shape antenna which could be embedded in the metal box was introduced. The simulation results showed that the S11 of the designed antenna was less than -10 dB in the broad band from 0.8 GHz to 3.2 GHz, while the gain was greater than 3 dBi. Obviously, the designed antenna could meet the performance requirements of the train radio communication system for the wideband and conformal shape performance.
