• Antenna design often seen as black art, but brute-force GPU approach explored. • Janne, novice, used VNA and GPU-based FDTD to simulate and optimize antennas. • Leveraged LLMs to generate code, validate with openEMS, and create reward functions. • Resulting designs were unconventional, matching modeled performance but underperforming on PCBs. • Project demonstrates feasibility of AI-driven inverse design, though practical results need refinement. • Code available on GitHub for experimentation and deeper exploration by experienced engineers.

Article Summaries:

  • Antenna design is often referred to as a black art or witchcraft, even by those experienced in the space. To that end, [Janne] wondered-could years of honed skill be replaced by bruteforcing the problem with the aid of some GPUs? Iterative experiments ensued. [Janne]’s experience in antenna design was virtually non-existent prior to starting, having a VNA on hand but no other knowledge of the craft. Formerly, this was worked around by simply copying vendor reference designs when putting antennas on PCBs. However, knowing that sometimes a need for something specific arises, they wanted a tool t
