| 摘 要： | 根据微带天线的辐射原理,设计一种谐振频率为2.47 GHz的矩形微带天线,并对微带天线频带的展宽方法进行了研究。通过附加贴片来修改等效谐振电路,使其具有多个谐振点,从而扩展阻抗带宽,仿真结果表明该天线的阻抗带宽达到了12%(300 MHz)。该天线具有体积小、宽频带和低抛面等特点,可作为无线传感网络节点的终端天线,具有一定的工程应用价值。

| Abstract: | According to the radiation principle of microstrip antenna,a rectangular microstrip antenna is designed.The resonant frequency of microstrip antenna is 2.47 GHz.The method of broadening the bandwidth of antenna is also discussed.Through adding an additional patch,the equivalent resonant circuit to be varied gets more resonance paints to extend the bandwidth of microstrip antenna.Simulation results show that the antenna has a bandwidth of 12%(300 MHz).The antenna designed in this way has advantage of small size,broadband and low-cast side.It can be used as terminal antenna for wireless sensor networks with high value of application in engineering. |
