The invention discloses a double-open-loop miniaturized
equalizer. The double-open-loop miniaturized
equalizer comprises a micro-strip layer, a
dielectric layer and a
metal layer which are sequentially stacked from top to bottom; the micro-strip layer further comprises a first double-open-loop
resonator and a second double-open-loop
resonator with the same structure; one end of a first open ring surface micro-strip is connected with a first
resistor, and the other end of the first open ring surface micro-strip is of an open ring structure; the circle center of the open ring structure of the first open ring surface micro-strip and the circle center of the open ring structure of a first inner open ring surface micro-strip are located at the same point; and one end of the first inner open ring surface micro-strip is connected with the
metal layer, and the other end of the first inner open ring surface micro-strip is of an open ring structure. According to the double-open-loop miniaturizedequalizer provided by the invention, a novel resonant structure is adopted as a resonant unit of the double-open-loop miniaturized
equalizer, the structure is simple and the size is small; since thestructure has a lot of variable parameters, the double-open-loop miniaturized equalizer is more flexible than a traditional
transmission line structure
resonator, and can realize a complicated
equalization curve; and besides, the double-open-loop miniaturized equalizer has a larger
equalization amount and a large bandwidth.
