Filtering Power Divider with Wide Stopband Using Open-Stub Loaded Coupled-Line and Hybrid Microstrip T-Stub/DGS Cell

摘要

In this paper, a compact filtering Wilkinson power divider exhibiting the high isolation with an ultra-wideband spurious suppression is proposed. The open-stub loaded coupled-line (OSLCL) is introduced for the power divider design to obtain the passband enhancement with two transmission zeros close to center frequency of
