摘　　要：A broadband microstrip patch antenna was analyzed and designed.Full wave analysis method(FWAM) was employed to show that a stacked microstrip dual patch antenna(SMDPA) might have a much wider bandwidth than that of the ordinanry uni patch one.By means of discrete complex image theory(DCIT),the Sommerfeld integrals (SI) involved were accurately calculated at a speed several hundred times faster than numerical integration method(NIM).The feeding structure of the SMDPA was then improved and the bandwidth was extended to about 22% or more for voltage standing wave ratio (VSWR)s≤2 Finally,a matching network was constructed to obtain a bandwidth of about 25% for s≤1.5.分析和设计了一种宽频带微带贴片天线应用全波分析法（ＦＷＡＭ）研究表明，双层重叠微带贴片天线（ＳＭＤＰＡ）具有比普通单贴片微带天线宽得多的带宽利用离散复镜像理论（ＤＣＩＴ）精确计算了所涉及的索末菲积分（ＳＩ），其速度比数值积分法（ＮＩＭ）快数百倍通过改进ＳＭＤＰＡ的馈电结构，使其带宽在ｓ≤２时展宽至２２％以上最后，设计了匹配网络。
