摘要：
Two microstrip tri-section filters with mixed couplings are presented, respectively. The location of the additional transmission zero can be adjusted by changing the nature of direct couplings. Inter-digital coupling structure and defected ground structure (DGS) are adopted to miniaturize their geometries. Wide stopband is obtained in each of them because of the suppression of the first spurious passband. The measured S-parameters of the realized filters agree well with the simulated results, with their high performance demonstrated.
