Abstract
FILTRO DE MICROFITA. A presente invenção refere-se a um filtro de microfita, incluindo uma pluralidade de unidades de filtro de microfita dispostas linearmente, onde cada uma das unidades de filtro de microfita inclui uma primeira microfita e uma segunda microfita, a primeira microfita é fechada para formar um espaço de acomodação, a primeira microfita é ainda provida com uma abertura comunicando com o espaço de acomodação, uma extremidade da segunda microfita está localizada no espaço de acomodação e conectada à primeira microfita e a outra extremidade da segunda microfita passa pela abertura para se estender para fora do espaço de acomodação. O filtro de microfita tem uma função de supressão forte fora de banda de uma frequência ultrapróxima, e um valor Q do filtro de microfita é aumentado.MICROSTRIP FILTER. The present invention relates to a microstrip filter, including a plurality of linearly arranged microstrip filter units, where each of the microstrip filter units includes a first microstrip and a second microstrip, the first microstrip is closed to form a accommodation space, the first microstrip is further provided with an opening communicating with the accommodation space, one end of the second microstrip is located in the accommodation space and connected to the first microstrip and the other end of the second microstrip passes through the opening to extend towards outside the accommodation space. The microstrip filter has a strong out-of-band suppression function of an ultra-close frequency, and a Q value of the microstrip filter is increased.
