Abstract :
The spectral domain full-wave analysis and the moment method were used to analyze coplanar parasitic subarrays. The first configuration studies was a radiating-edge-gap-coupled three-element subarray. It was found that convergence problems are encountered if entire domain cavity-mode basis functions are used. Consequently, piecewise-sinusoidal (PWS) expansion modes were used instead. The gap widths for the five cases considered were in multiples of each other, in the range of 0.0825-1.32 cm.<>
