How to Design and Simulate PCB Antenna
Why people recommend it
Offered as a MATLAB tutorial on designing and simulating PCB antennas, including how the presence of dielectric material near an antenna changes its behaviour.
Watch for: Needs a recent MATLAB licence
In their words
Not a fan of non-open source/free software but you can use Matlab, the last years they implemented PCB antenna design tools, (watch tutorial here)
