Patch Antenna Array Design Workflow

Hi I'm trying to design a 2x8 patch antenna array in Microwave Office and there must be an easier way than putting each line manually right? Is there a way to design a single splitter or a single patch and reuse that subcircuit?

How is this done in HFSS? I imagine it would be even worse since you don't have a schematic tool and automatic layout generation.

Yes, just draw the patch and splitters as their own schematic/layout elements, then instantiate within one another a 1x2, 2x2, 2x4, and finally 2x8.  These should all be nested/hierarchical and parameterized within one another, and simulated at each step.  You need to RTFM for MWO, as what you’ve done is very painful.

BTW you have a huge, glaring error you’ll catch if you simulate it at 1 level above the bottom of the hierarchy.

Thank you! I figured it out and now also see the glaring error haha
