How to Define Differential (Balanced) Transmission Lines in Antenna Toolbox Using customAntenna?

Hello everyone,

I’m working with the Antenna Toolbox in MATLAB and would like to model differential transmission lines to design a balanced-to-unbalanced converter (balun). Specifically, I want to define a pair of coupled lines (or something equivalent) using the customAntenna module.

Has anyone set up differential lines in the Antenna Toolbox before? If so, I’d greatly appreciate any recommended workflows, code snippets, or guidance on the best practices.

Thank you in advance for your help!
