HFSS15: Defining Antenna Arrays

Define a regular or custom antenna array when you want HFSS to compute antenna array radiation patterns and antenna parameters for designs that have only a single array element. HFSS models the array radiation pattern by applying an "array factor" to the single element’s pattern when far fields are calculated.

The "regular uniform array" geometry defines a finite 2D array of uniformly spaced, equal-amplitude elements. This is a natural specification after phased array applications. The "custom array" geometry defines an arbitrary array of identical elements distributed in 3D space with individual user-specified complex weights.

If you define an antenna array, the antenna setup icon in Project tree changes from a single antenna an array icon.
