This communication presents a filtering antenna with high selectivity using multiple coupling
path from source/load to resonators. The high selectivity of the filtering antenna's boresight …

This paper presents tunable balanced bandpass filters with constant fractional bandwidth
(FBW) and constant absolute bandwidth (ABW), respectively. The equivalent differential-and …

A compact microstrip quadruplexer with high isolation is presented in this letter. The
quadruplexer consists of a distributed coupling feeding line, output feeding lines and …

This brief presents a new approach for designing compact bandpass filters (BPFs) with
harmonic suppression using quarter-wavelength stepped-impedance resonators (SIRs). The …

This paper proposes a simple and effective method to designing wide-stopband bandpass
filters and diplexers using uniform impedance resonators. Microstrip terminated parallel …

This paper presents a novel compact low-temperature cofired ceramic (LTCC) bandpass
filter (BPF) with wide stopband and high selectivity. The proposed circuit consists of two …

A multilayer dual-band bandpass filter with two independent paths combined between
common input and output ports is proposed in this letter. Slot-coupled resonators and …

A dual-band filter of a large frequency ratio is proposed, studied, and developed in this
article, which is based on mode composite coplanar waveguide (MCCPW). Both low and …

This article discusses the patterns of coupling coefficients between stripline resonators in
combline and pseudocombline structures. It was established that there is an electromagnetic …

The design techniques and topologies of multiband bandpass filters (MBPFs) have been
investigated in insubstantial amount of literature. However, MBPFs with specific bandwidth …
