Description

technical field [0001] The invention relates to the technical field of microwave passive devices, in particular to a double-passband power division filter using a single-layer circular patch. Background technique [0002] Modern wireless communication systems require compact and high performance power division bandpass filters. With the development of multi-band and multi-standard modern wireless communication systems, the demand for multi-band microwave components is increasing. Among them, dual-band filter power dividers (DB-FPDs) have been receiving much attention. In the past few years, researchers in related research directions have made many efforts to develop them. In order to realize the functions that people need, in literature 1 [P.Wen, Z.W.Ma, H.W.Liu, S.S.Zhu, B.P.Ren, Y.Song, X.L.Wang, M.Ohira, "Dual-band filtering power divider using dual-resonance resonators with ultrawide stopband and good isolation.”IEEEMicrow.Wireless Compon.Lett.,vol.29,no.2,pp.101-103,...
