Reply to Comments on "Novel ultra-wideband bandpass filter using shorted coupled lines and transversal transmission line"

In replying to the comment on their original paper [ibid., vol. 21, no. 9 pp 510, 2011] the authors state their appreciation of the good work previously published by Sanchez-Soriano et al. (2009) in the UWB bandpass filter (BPF) structure realized with two shorted coupled lines and a 270° transmission line. It is noted that the earlier work was not found in a literature search before the authors´ article was published.
