Normally when the loop width of the loop type FSS increases, the total conductive area will be larger, causing the inductance to increase. When the inductance increases, the resonant frequency will decrease. But in my simulation, I saw the opposite result. I looked at different studies in the literature and they all found the same result as the simulation results. But I don't understand how the resonant frequency increases when the loop width increases.
I think you mean that the hole in the middle of the loop got smaller. This will reduce the mean circumference of the loop and increase the resonant frequency. Also, I think that a thicker conductor will usually have a lower inductance, not a higher inductance.
You can check the attached png file. I mean the value of 'w' which depicted in Figure. When the w value increase, the total area of the conducting strip increase. Doesn't that mean that more magnetic fields can be generated?
What is the relationship between the conducting area and inductance?
Btw all the other geometric parameters is kept constant.
When w increases the hole in the centre gets smaller. The track gets wider. Thick wires and tracks have less inductance than thin wires. Smaller inductance means higher resonant frequency.
Alternatively the mean circumference becomes smaller as w increases, so the resonant wavelength becomes smaller and the resonant frequency increases.
