Abstrakt: A compact wideband bandpass filter at the centre frequency of 5.77 GHz with 78% fractional bandwidth is presented. An especial coupling structure along with a novel triple mode spiral resonator designed based on modal analysis is used to provide a flat wide passband with excellent skirt characteristics. To verify the efficiency of the filter, a prototype is fabricated, tested and compared with some of the most recent works. [ABSTRACT FROM AUTHOR]
