【摘要】 随着无线通信系统的快速发展,具有宽带宽、增益高、尺寸小的超宽带微带天线受到广泛的关注。利用波概念迭代法(WCIP)结合传输线理论仿真了双层和三层结构的超宽带微带贴片天线,计算了该天线的回波损耗、驻波比等参数;对比分析了WCIP在计算效率上的优势;分析了电路层数对天线带宽的影响,发现增加电路层数是天线带宽展宽的一个有效途径。同时,与软件HFSS仿真结果的对比验证了WCIP分析微波多层电路的正确性和有效性。更多还原

【Abstract】 With the rapid development of wireless communication system,the antenna with wide bandwidth,high gain and small dimension is extensively concerned.In this paper,wave concept iterative process(WCIP)is presented with transmission lines theory to analyze two ultra wideband antennas with two and three layer structure.The circuit characteristic parameters and voltage standing wave ratio,are calculated by the method effectively.The calculation effect of WCIP is also analyzed by comparison with multiple-input multiple-output(MOM) and finite element method.The results show good agreement compared with the HFSS simulation data,which proves the correctness and effectiveness of WCIP.Besides,by compared the bandwidths of the two antennas,the influence of bandwidth by circuit layers is analyzed.更多还原
