对电阻加载微带贴片天线进行了理论分析,并采用了矩量法和有限差分时域法进行了仿真计算,然后进行了试验测试,从这三个方面均可以看出电阻加载方法虽然能够提高微带贴片天线的带宽,但也同时使得天线的效率有较大的降低.为此提出一种新型结构的电阻加载微带贴片天线,并对该天线模型进行了分析和试验测试,结果表明:这种新型结构微带天线可以通过调整加载电阻大小和位置来控制天线的效率和带宽,使天线的效率和带宽能相互兼顾以满足在实际工程中的需要.
The resistive loading microstrip patch antenna is analyzed theoretically, and the method of moment method and finite difference time domain method are used to carry out the simulation calculation. Then the test is carried out. From these three aspects, it can be seen that the resistance loading method can Improve the bandwidth of the microstrip patch antenna but also reduce the efficiency of the antenna at the same time.Therefore, a new type of resistively loaded microstrip patch antenna is proposed and the antenna model is analyzed and tested. The results show that the new structure of microstrip antenna can control the efficiency and bandwidth of the antenna by adjusting the size and position of the loading resistor so that the efficiency and bandwidth of the antenna can be balanced with each other to meet the needs in practical engineering.
