“…However; a notch band was not provided to eliminate the interference frequencies to FCC band. In addition to the presented analyses in the cited literatures, some other analyses based on lumped equivalent circuit have been proposed [16]. In this paper a novel compact UWB band pass filter along with all theoretical aspects are presented.…”

“…Compact size, sharp roll-off, and wide stopband are the current trends in the design of microstrip LPFs [2]- [6]. Due to the inherent characteristics of a microstrip line, conventional designs of microstrip LPFs fail to satisfy the requirements of compact size and wide stopband [1].…”

The stepped-impedance lowpass filter is modified by replacing the low-impedance lines with lowpass transmission lines. The modified stepped-impedance lowpass filter is called a multistub lowpass filter because it is largely composed of open-circuited stubs. For experimental verification of the multi-stub filters, we design a 1 GHz seventh-order Butterworth LPF. The proof-of-concept prototype is a compact design that fits into a circuit size of on an RO4003 substrate. The measurement results show that the multi-stub lowpass filter retains the characteristics of a Butterworth filter in the passband, while substantially improves the performance in the transition and stopband regions. It achieves state-of-the-art performance compared to lowpass filters in the literature. Index Terms-Lowpass filter (LPF), microstrip line, steppedimpedance.
