Hi everyone I want to analyze the effect of slot on the resonance frequency of a microstrip patch antenna. do anyone know about articles where resonance frequency formula is updated to accommodate the effect of slot
Best regards and a good day.
I was able to find these two papers on the topic:Conference Paper Transmission line model design formula for microstrip antenn...

thanks a lot
Hello,
First check the slot position is correct using surface wave current, then simulate it.
Thanks,
