摘要
Complementary split ring resonators are used to design compact, low insertion loss (IL), low pass filter with sharp cut-off. A prototype filter implementing area is 0.23 lambda(g) x 0.09 lambda(g), lambda(g) being the guided wavelength at 3-dB cut-off frequency (f(c)) 1.887 GHz. Maximum IL is within 0.5 dB up to 1.717 GHz and 20-dB stopband extends up to 3.4 f(c).
