- This letter presents a novel band rejection filter (BRF) using a pair of spur-lines or double spur-lines with an opposite direction, which is embedded in a transmission line. The slot length (L1) of double spur-lines determines a rejection band and the distance (L2) between the end points of each spur-line determines the position of a pass band, which is at the left or right side of a rejection band, respectively. That is, if L2 is shorter than L1, the right side of a pass band can be properly suppressed, otherwise if L2 is longer than L1, the left side of a pass band can be suppressed. Two novel kinds of BRFs were realized at Ku-band using soft Teflon substrate to verify the validity of the proposed structure. The measured performance was well agreed with the simulated one. © 2010 Wiley Periodicals, Inc.
