Abstract

In this article, a compact bandpass filter is proposed for lower band (3.1–4.9 GHz) of ultra‐wideband applications. The filter is mainly composed of a pseudo‐interdigital wideband bandpass filter (PI‐WBF) and a multiple transmission‐zeros structure (MTZS), being a bandstop filter. By using the MTZS, multiple transmission zeros can be located in the upper stopband of the PI‐WBF. The design procedure is discussed in detail. The designed filter was fabricated and measured. Measured results also have a good agreement with the simulated results. © 2007 Wiley Periodicals, Inc.

## Abstract In this paper, we propose a novel parallel‐coupled microstrip bandpass filter with a wide stopband. The proposed bandpass filter with spur lines provides a deep and wide stopband because spur lines can provide deep stopband characteristics in some frequency bands. Also, the experimental
