Abstract
A square spiral placed on a dielectric slab which is backed by a ground plane is analyzed. The spectral domain Green's functions for a current element on a grounded dielectric slab are used to develop an integral equation which is solved by the method of moments. In this formulation, the effects of the dielectric material are rigorously modeled. The current density on one arm of the square microstrip spiral at 6.0 GHz is shown as a function of subdomain number and compares favorably to the results found in H. Nakano et al. (1986) for the Archimedean spiral. The gain, axial ratio, and input impedance of the square microstrip spiral are shown as functions of frequency and also compare favorably to the results for the Archimedean spiral.<>
分析了以接地面为背的介电板上的方形螺旋。利用介电接地板上电流单元的谱域格林函数，建立了用矩量法求解的积分方程。在这个公式中，电介质材料的影响是严格模拟的。6.0 GHz方形微带螺旋单臂上的电流密度显示为子域数的函数，与H. Nakano et al.(1986)在阿基米德螺旋上发现的结果比较有利。方形微带螺旋的增益、轴比和输入阻抗显示为频率的函数，并且与阿基米德螺旋的结果相比较也很好。
