Equiripple design of low‐pass filter using stub‐loaded Z‐shaped coupled‐line section
IET Microwaves, Antennas &Propagation, Volume 15, Issue 15, Page 1899-1913, 16 December 2021., 2021 Abstract Design procedure of a novel transmission line low‐pass filter is presented. The filter has a flexible rejection response for a prescribed cut‐off frequency and an in‐band ripple factor. It is compact by using a Z‐shaped coupled‐line section, which is loaded with open‐circuited stubs.

IET Microwaves, Antennas &Propagation, Volume 15, Issue 9, Page 995-1008, 29 July 2021., 2021 Abstract Analysis and design of a wideband bandstop filter with multi‐transmission zeros (TZs) and reflection zeros (RZs) are presented. The proposed topology consists of N‐1 shunt open‐circuited stubs (OCSs) cascaded through N‐sections of transmission lines, and two M‐sections of OCSs are shunted at two output ports, respectively.
