In this letter, a novel design of microstrip diplexer used for ultra‐wideband communication has been proposed. The primary structure of the diplexer comprises two different parallel‐coupled line structures with slot‐line resonators (SLRs), which are used for generating the filtering response with high‐channel selectivity. The diplexer is designed to have the lower and higher passband with the operating frequencies at 3.2–4.8 GHz and 6.5–9.8 GHz, respectively. Experimental results also show a good agreement with the simulated results. © 2009 Wiley Periodicals, Inc.
