| description | This paper presents the characteristics of a miniaturized microstrip filter, which has two separate coupling paths: electric coupling path and magnetic coupling path between two resonators. Either magnetic coupling or electric coupling in two
paths can be dominant in the total coupling coefficient of the inter-stage resonators with the similar configuration, but different
positions of transmission zero points (ZPs). Based on the proposed filter topology, second- and fourth-order filters have been designed and fabricated for the first time. Advantages of using this type of
filter are not only its low insertion loss and much more compact size, but also its controllable transmission ZPs. |
