摘要: In this paper, dual-mode microstrip ring bandpass filters with new interdigital side-coupling structure are presented. The scheme has much lower insertion and return losses than any other structure. Dual-mode one or two local resonant split (LRS) circuits centered at 2.2 2.05 GHz show 3-dB bandwidths of only 70 75 MHz, the -2.75 -2.12 dB, -19.48 -19.65 respectively.
