Abstract :
In this paper, a microstrip bandpass filter based on cross-coupled is designed. Ceramic substrate with high dielectric constant and SIR structure are adopted. Because of Quarter-Wave and ceramic substrate, the whole size of the filter can be fabricated very small. Specifically, when the center frequency is 3.5GHz, its volume is 7mm*6.2mm*0.127mm. Besides the compact size, wide stopband and narrow passband makes it an excellent frequency-selecting filter.
