Some questions on Ring Resonator Circuits..

[jaeway]

Few questions here..

1) How do we determine the width of the square loop resonator if we set our resonant frequency at let's say 2.5 GHz ? Is there any formula to this? Or the width of the loop is actually self set?

2) for nλ = 2πr , n is the mode number, and so what does this mode number refers to? I know it is something to do with TMmnl where m is root number of each n and l is 0. How to determine what mode ?

Thanks

hi
u can find this formula in book s of plump element by bahl or ring microwave by K.cheng
