What it can do

Attaches to a running AEDT session on the gRPC port shown in its Message Manager.
Builds a fully parametric coax-fed patch antenna or a centre-fed half-wave dipole for a given frequency, with boundaries, ports, setup, sweeps, far-field sphere and reports.
Adds wave and lumped ports, adaptive setups and frequency sweeps, solves, and reads S-parameters and far-field patterns.
Runs arbitrary PyAEDT code as a background job that the agent polls for results.

Limitations

Install and configuration steps are written for Windows paths only.
Dedicated geometry tools are limited to boxes, cylinders and spheres.
No licence file in the repository; the README states Apache 2.0.
