In this video presentation, Remcom discusses analyzing and optimizing an aperture coupled 1x4 patch antenna array with a compact, fan-shaped feeding network for operation in 60 GHz band using Remcom’s full-wave electromagnetic simulation product, XFdtd. We also demonstrate superposition and antenna array optimization. The superposition simulation provides a means for checking the performance of individual elements in an array, each with a different input power and phase. The array optimization feature allows users to estimate the excitation for each element in the array for a specified EIRP. Further, the total spatial coverage of designed phased arrays will be accurately estimated.
