摘要
在设计分析微带无线时,供选择的方法较多,而积分方程法是一种较严格的方法.这种方法经常采用格林函数建立场与源的积分关系,求解过程很复杂.在分析矩形微带天线的阻抗时,为了将无穷区间的矩阵元素积分问题变成离散的有限继问题,采用了适当的逐段多项式函数,如样条函数来逼近,将微带天线设计中的某些积分化为逐段多项式函数因而,可以将高维积分变为较低维的积分,产生近似的有限维问题,从而简化了运算过程.
There are many ways to design a microstrip antenna, and the integral equation is offen much mere precise than other methods. Because integral relations between source points and observation points are relevant to Green's Function, the solution of the equatison is very difficult to obtain. The article describes a method which car turns the infinite integrals of matrix element into lower dimensional integral. By using spline function, the integrand and calculation process are all simplified.
