It belongs with the iot & wireless and science & space designs in this gallery.

From the project

PCB simulation for KiCad: power and signal integrity, thermal analysis, with capability to add extensions and be able to perform basic EM simulations

This example uses the open iot-esp-eth-ind board from uysan/iot-esp-eth, pinned at upstream commit 0b9eb3500cd8ccdd6193c81e1406bfe9281d88e6 and board SHA-256 3199ce0a25f8987020e716d82a4a35d9b6b04541d33b2f2e46406376713eab33. The board is licensed under CERN-OHL-P-2.0. The source schematics, KiCad project, upstream openEMS script and measured Touchstone file are in source/. The board has four copper layers; the antenna is formed from filled, unnetted F.Cu graphic polygons, a short to ground, and a feed and matching network. Those distinctions matter for both the viewport and electromagnetic…
