As you can see in attached photo, for a U-slot patch antenna the dimensions are depicted.
Is there any mathematical formulas to calculate the exact position and dimensions of the slot?
I know I can use simulation software to optimize the position and dimensions of the slot for the desired frequency.
but I'm looking for a mathematical and logical solution for designing such antenna.
I'm sure this is the question of so many other young researchers.
thanks in advance for your help.
