Circuit Modelling of Bandpass/Channel Filter with Microstrip Implementation
Indonesian Journal of Electrical Engineering and Informatics (IJEEI), 2020 This paper presents a step-by-step approach to the design of bandpass/channel filters. A 3-pole Chebyshev bandpass filter (BPF) with centre frequency of 2.6 GHz, fractional bandwidth of 3%, passband ripple of 0.04321 dB and return loss of 20 dB has been designed, implemented, and simulated.

Microstrip Diplexers With Double-Stub Bandpass Filters
, 2011 This paper presents a microstrip diplexer using two Double-Stub Band-Pass Filters (DS-BPFs), composed of several double-stubs connected to a main microstrip line. Each DS-BPF has a null at the center frequency of the other. Therefore, these types of filters are suitable for diplexers with two near frequencies.
