Fr= 1/2π (LC)^1/2

Where L = e D(phi)/dt and C= A epselon zero k/d

These equations indicates that as L increases, e increases, dielectric constant increases, the resonant frequency reduces.

Hope it will help,

Thanks

Dear Ma'm,

Dear Ma'm,every much. Its quite useful..Can you reger any literature on basics of DGS..Actually i am applying DGS to my SIW bandpass filter

ThanksREgards
