摘要：
A novel dual-band filter using slotline and microstrip resonators is proposed. By introducing slotline resonators on the ground of conventional microstrip resonator, the filter provides two transmission paths for RF signals. Each path generates its own passband. Both microstrip resonator and slotline resonators share the input and output ports without any external impedance-matching network. Deep rejection between the two passbands is obtained due to a transmission zero located between them. The filter has the advantages of low insertion loss, compact size, and good selectivity. The simulated and measured results are presented and show good agreements. (c) 2007 Wiley Periodicals, Inc.
