Hello,
in google I found one document with some research of patch with notch antenna (document attached). This antenna should have two "resonances" - one at ~2.7GHz, second "resonance" depends from notch size and is ~4.4GHz with 6x6mm notch.
I do simulation with Ansoft HFSS of that antenna. First "resonance" is at ~3GHz, second "resonance" doesn't depend from notch size and is ~5GHz. What's wrong in simulation model (attached)? Does the feeding is correct? Maybe some problems with air arround antenna?
Or maybe that research has some errors and lie to avoid copying?
