提出了一种双层宽带矩形微带贴片天线，利用基于有限积分法的软件研究了寄生贴片尺寸以及两叠层之间的气隙对天线性能的影响。优化后的双层天线的带宽相对于中心频率5.5GHz提高了23.6%，而传统贴片天线的带宽为4.5%。此外，双层微带天线的增益达到了以上在5.1GHz至6.0GHz频率范围内为6dB，覆盖了WLAN的IEEE802.11a标准(5.15~5.825GHz)。实验结果与仿真结果一致。
A double-layer broadband rectangular microstrip patch antenna is presented.The effects of size of the parasitic patch as well as the air gap between two stacked layers on the performance of the antenna are investigated using a software based on finite integral method.The bandwidth of the optimized double-layer antenna is enhanced to 23.6% with respect to the center frequency of 5.5GHz,compared to 4.5% of a conventional patch antenna.Moreover,the gain of the double-layer microstrip antenna reaches more than 6dB at the frequency range from 5.1GHz to 6.0GHz which covers the IEEE802.11a standard(5.15~5.825GHz) for WLAN.Experimental results are in agreement with the simulation results.
