摘要: The invention discloses a microstrip band-pass filter, comprising: resonant unit, wherein the unit comprises first second third and fourth arranged in sequence; each has length of quarter wavelength, two adjacent units are coupled to other; cross-coupled line having twoends non-adjacent elements, respectively, produce transmission zeros at high frequency and/or low frequency. aims providing bandpass which can generate arbitrary positions through flexibly cross-coupling lines, thereby improving suppression degree realizing miniaturization filter by wavelength.
