摘要
根据修改的微带天线的腔模理论,利用电磁场理论推导了悬置矩形微带天线的谐振频率的理论计算公式,为了减小微带天线制作中的各种因素所引起的谐振频率的偏移,对微带天线的不准确性进行误差分析和仿真研究,结果表明,各种制造公差对谐振频率的影响程度不同。
Based on the modified theory of cavity model, a theoretical expression of resonant frequency of suspensive rectangular microstrip antennas is deduced by using electromagnetic field theory. At the same time, to min-ish frequency shift of microstrip antennas caused by all sorts of factors in the manufacturing, error analysis and simulation are carried out about the inaccuracy of microstrip antennas. It shows that all sorts of manufacturing tolerance make different impact on the frequency.
