| 摘 要： | 介绍了半波谐振贴片的理论,并利用HFSS分别对采用微带和同轴两种方式馈电的中心频率为12GHZ的平面贴片天线进行了仿真.仿真结果表明:当改变微带与同轴传输线馈电位置时,对于微带馈电方式,要实现单频点,取贴片的长边中点效果较好;如果偏离该中心点,将具有双频点特性.而采用同轴馈电时,所研究的几个馈电点位置中也是贴片长边中点相对较好,如偏离该中心点,频率将偏离中心频率.

| Abstract: | The theory of half wave length antennas with a center frequency of 12GHz are simulated with the software HFSS, fed by coax line and micro-strip line respectively. The results of simulating the same patch antenna with different feeding positions show that the center-fed patch antenna has a better performance in designing single resonance frequency antenna. Another resonance frequency appears if the feeding position is away from the center point of the patch long-side. |
